  • Questions of accuracy around Washington Post plan
    The incoming editor of <em>The Washington Post</em>, Robert Winnett, has withdrawn from the job and will remain in the U.K.
    The Washington Post is experimenting with personalized news podcasts created by AI.

    Topline:

    The Washington Post's new offering, "Your Personal Podcast," uses artificial intelligence to customize podcasts for its users, blending the algorithm you might find in a news feed with the convenience of portable audio.

    What critics are saying: The AI podcast immediately made headlines — and drew criticisms from people questioning its accuracy, and the motives behind it.

    What the Post is saying: Bailey Kattleman, head of product and design at the Post, calls it "an AI-powered audio briefing experience" — and one that will soon let listeners talk back to it.

    Read on ... for more details and answers to the biggest questions about this new experiment.

    It's not your mother's podcast — or your father's, or anyone else's. The Washington Post's new offering, "Your Personal Podcast," uses artificial intelligence to customize podcasts for its users, blending the algorithm you might find in a news feed with the convenience of portable audio.

    The podcast is "personalized automatically based on your reading history" of Post articles, the newspaper says on its help page. Listeners also have some control: At the click of a button, they can alter their podcast's topic mix — or even swap its computer-generated "hosts."

    The AI podcast immediately made headlines — and drew criticisms from people questioning its accuracy, and the motives behind it.

    Nicholas Quah, a critic and staff writer for Vulture and New York magazine who writes a newsletter about podcasts, says the AI podcast is an example of the Post's wide-ranging digital experiments — but one that didn't go quite right.

    "This is one of many technologically, digitally oriented experiments that they're doing" that is aimed at "getting more audience, breaking into new demographics," he says. Those broader efforts range from a generative AI tool for readers to a digital publishing platform. But in this case, Quah adds, "It feels like it's compromising the core idea of what the news product is."

    On that help page, the newspaper stresses that the podcast is in its early beta phase and "is not a traditional editorial podcast."

    Bailey Kattleman, head of product and design at the Post, calls it "an AI-powered audio briefing experience" — and one that will soon let listeners talk back to it.

    "In an upcoming release, they'll be able to actually interact and ask follow up questions to dig in deeper to what they've just heard," Kattleman says in an interview with NPR.

    As technically sophisticated as that sounds, there are many questions about the new podcast's accuracy — even its ability to correctly pronounce the names of Post journalists it cites. Semafor reported that errors, cited by staffers at the Post, included "misattributing or inventing quotes and inserting commentary, such as interpreting a source's quotes" as the paper's own stance.

    In the newspaper's app, a note advises listeners to "verify information" by checking the podcast against its source material.

    In a statement, the Washington Post Guild — which represents newsroom employees and other staff — tells NPR, "We are concerned about this new product and its rollout," alleging that it undermines the Post's mission and its journalists' work.

    Citing the paper's standing practice of issuing a correction if a story contains an error, the guild added, "why would we support any technology that is held to a different, lower standard?"

    So, why is the Post rolling out an AI podcast? And will other news and audio outlets follow its lead?

    Here are some questions, and answers:

    Isn't AI podcasting already a thing?

    "The Post has certainly gone out on a ledge here among U.S. legacy publishers," Andrew Deck tells NPR. But he adds that the newspaper isn't the first to experiment with AI-generated podcasts in the wider news industry.

    Deck, who writes about journalism and AI for Harvard University's Nieman Lab, points to examples such as the BBC's My Club Daily, an AI-generated soccer podcast that lets users hear content related to their favorite club. In 2023, he adds, "a Swiss public broadcaster used voice clones of real radio hosts on the air."

    News outlets have also long offered an automated feature that converts text articles into computer-generated voices.

    Even outside of the news industry, AI tools for creating podcasts and other audio are more accessible than ever. Some promise to streamline the editing process, while others can synthesize documents or websites into what sounds like a podcast conversation.

    Why do publishers want to experiment with AI podcasts?

    "It's cost-effective," says Gabriel Soto, senior director of research at Edison Research, which tracks the podcast industry. "You cut out many of the resources and people needed to produce a podcast (studios, writers, editors, and the host themselves)."

    And if a brand can create a successful AI virtual podcast in today's highly competitive podcasting market, Soto adds, it could become a valuable intellectual property in the future.

    Deck says that if the Post's experiment works, the newspaper "may be able to significantly scale up and expand its audio journalism offerings, without investing in the labor that would normally be required to expand."

    In an interview, Kattleman stresses the new product isn't meant to replace traditional podcasts: "We think they have a unique and enduring role, and that's not going away at the Post."

    What's unique about the Post AI podcast?

    For Deck, the level of customization it promises is an innovation. Being able to tailor a podcast specific to one person, he says, "is arguably beyond what any podcast team in journalism right now can produce manually."

    In an example the Post published, listeners can choose from voice options with names like "Charlie and Lucy" and "Bert and Ernie."

    Kattleman says her team was working from the idea that for an audience, there isn't a "one size fits all" when it comes to AI and journalism.

    "Some people want that really straight briefing style; some people prefer something more conversational and more voicey," she says.

    Quah says that adding an AI podcast is a bid to make stories accessible to a broader audience.

    He says that with the podcast, the Post seems to be trying to reach young people who "don't want to read anymore, they just want to listen to the news."

    A key goal, Kattleman says, is to make podcasts more flexible, to appeal to younger listeners who are on the go.

    Outlining the process behind the Post's AI podcast, Kattleman says, "Everything is based on Washington Post journalism."

    An LLM, or large language model, converts a story into a short audio script, she says. A second LLM then vets the script for accuracy. After the final script is stitched together, Kattleman adds, the voice narrates the episode.

    Will listeners embrace an AI news podcast?

    Soto, of Edison Research, says that 1 in 5 podcast consumers say they've listened to an AI-narrated podcast.

    But, he adds that for podcast listeners, "many prefer the human connection, accepting AI tools to assist in creating the content, but not in executing or hosting the podcast."

    The new AI podcast reminds Deck a bit of the hyper-personalized choices for users offered by TikTok and other social media.

    "There is a level of familiarity
    and, arguably, comfort with algorithmic curation among younger audiences," he says.

    But while younger audiences tend to be tech savvy, many of them are also thoughtful about authenticity and connection.

    "Community is at the core of why people listen to podcasts," Soto says.

    Then there's the idea of a host or creator's personality, which drives engagement on TikTok and other platforms.

    "These creators have built a relationship with their audience — and maybe even trust — even if they haven't spoken to sources themselves," Deck says. "This type of news content is a far cry from the disembodied banter of AI podcast hosts."

    What are the potential downsides of AI podcasts?

    One big potential consequence is the loss of jobs — and for companies, the loss of talent.

    "The automation of it kind of erases the entire sort of voice performance industry," Quah says. "There are people who do this for a living," he adds, who could "produce higher quality versions of these recordings."

    There are also concerns that, if AI chooses a story and controls how it's presented, it might create an echo chamber, omitting context or skepticism that a journalist would likely provide.

    "AI-based news personalization tends to land firmly in the camp of delivering audiences what they want to know," Deck says.

    Deck says he's willing to give the Post's AI podcast a bit of time to see how it plays out. But Deck does have a chief concern: "I can say point blank, generative AI models hallucinate."

    And when AI models are wrong, he says, they're often confidently so.

    Blurring boundaries between human and AI voices could also raise questions of trust — a critical factor for a news organization.

    As Soto puts it, "What happens when your audience expects content from the real you and ends up finding AI instead?"

  • Timeline is agreed to shift from LAHSA to county

    Topline:

    The nonprofits that run the L.A. region's federally-funded homeless shelters, outreach teams and housing services will soon be overseen by a new government agency, under a deal a federal judge says he plans to approve next week.

    The significance: If approved, the shift will mark the biggest change in the control of federal homeless dollars in L.A. in decades.

    What it does: The proposed settlement would shift federal grants and duties from the troubled L.A. Homeless Services Authority (LAHSA) to the county government in stages, starting next month. LAHSA’s management of federal services dollars would end in June. The deal between LAHSA and the Trump administration keeps the region's request for roughly $240 million in new annual federal funding on track and adds tighter checks on how that money is spent.

    ‘Dereliction of duty’: “This has been an absolute past dereliction of duty by the federal government” and local governments, Carter said at a hearing Friday, referring to what he called decades of failure to properly oversee public homelessness dollars.

LAHSA’s management of federal dollars for homeless services would end in June. The deal between LAHSA and the Trump administration keeps the region's request for roughly $240 million in new annual federal funding on track and adds tighter checks on how that money is spent.

    U.S. District Judge David O. Carter said at a Friday hearing he would likely sign it Monday, ending LAHSA's lawsuit over the Trump administration’s June suspension of the agency.

    “This has been an absolute past dereliction of duty by the federal government” and local governments, Carter said, referring to what he called decades of failure to properly oversee homelessness dollars.

    “I choose now to turn this back to the proper governing bodies,” Carter said. "But please, this can never happen again."

    Citing past audits and reports, Carter said “HUD’s been on notice since 2007” of LAHSA’s oversight failures and “abandoned” its own oversight role.

    “I termed it a partnership in failure,” he added. “Local government turned an absolute blind eye to the distribution of these funds and transparency and accountability for these funds.”

    “And what is so sad and disappointing is, these funds were meant to serve the absolute most vulnerable in our society,” the judge added.

    LAHSA has faced major problems in recent years. Last year, an LAist investigation found the signature of LAHSA’s then-CEO, Va Lecia Adams Kellum, finalized a $2.1 million contract with the nonprofit where her husband was working in senior leadership, despite previously telling LAist she was “completely recused.”

    LAist also found the agency kept awarding millions in contract renewals to another nonprofit even after LAHSA’s own compliance team labeled it “high-risk” for, among other things, billing for services while reporting no enrolled participants. That group’s leader, Alex Soofer, recently pleaded guilty to diverting $2 million. Another nonprofit operator contracted with LAHSA, Michael Young, was arrested and charged by federal prosecutors with misappropriating millions of tax dollars, including allegedly siphoning $1 million into a high-end nightclub.

    Additionally, a 2024 L.A. County audit found LAHSA had mismanaged hundreds of millions in contracts for homeless services, often paying service providers late and failing to track whether services were provided.

    Under the deal, Carter would receive quarterly reports on progress and could intervene if one of the parties asks him to resolve a dispute.

    When control would shift

    The deal, on its own, does not change which nonprofits provide shelter, outreach and housing. It instead changes which government agency pays them and ensures they’re serving people as required.

    Here’s what the timeline will be if Carter follows through on approving the deal:

    • Within two weeks of this year's federal awards: Most new grants awarded to LAHSA will instead be managed by the county, not LAHSA.
    • Starting Dec. 1: Grants for programs that begin on or after that date move to the county before they start.
    • January 2027: LAHSA, which has overseen the homeless counts since 2005, runs the annual homeless count one last time. The county runs it after that.
    • By March 1, 2027: The county is approved to take over as the agency that applies for federal homelessness money for the whole region going forward, instead of LAHSA.
    • By April 1, 2027: The county takes over management from LAHSA of many federal grants for programs already underway that continue past June 2027.
    • By June 30, 2027: LAHSA finishes administering federal grants that end by this date.
    • By Dec. 31, 2027: The county takes over the region’s federally required database, known as HMIS, that tracks which homeless services each person receives. The county also takes over another system, known as CES, that matches people with taxpayer-funded housing. With that, LAHSA's last remaining federal roles end.
    • January 2028: The county conducts the annual homeless count, taking over that role from LAHSA.

    What the deal would mean for services

    The federal government’s attorneys said the goal is to have stronger oversight over homelessness spending, after many years of documented failures by LAHSA. Attorneys who struck the proposed settlement said in court Friday that the timeline was structured to ensure a smooth transition that doesn’t disrupt homeless services.

    The HMIS database and matching system, which caseworkers use to track clients and place them in homes, will switch over last to avoid disrupting services, said Shayla Myers, the lead attorney for the L.A. Continuum of Care, the body that coordinates federal homelessness funding and joined LAHSA in the lawsuit.

    For taxpayers, the deal adds safeguards on spending Carter has demanded for years. LAHSA must send invoices and spending records to the U.S. Department of Housing and Urban Development (HUD) before drawing grant money, and submit receipts afterward. A HUD contractor, Guidehouse, will review its books, and the county must follow the same rules for older grants it inherits. The parties will report to Carter every three months, until LAHSA no longer has any federal roles overseen by HUD.

    First Assistant U.S. Attorney Bill Essayli, whose office represents HUD, told LAist after the hearing that the county is probably the best equipped to take over, and scrutiny will be crucial.

    “Do I have amazing confidence in the county? No,” he said, noting that LAHSA is a joint city-county agency.

    “But we're going to verify that they are going to be good stewards of the tax money.” With LAHSA gone, he added, “The buck's going to stop at the county.”

    Under the proposed deal, LAHSA agrees to cooperate fully with HUD's investigations. A LAHSA attorney told the judge on Friday the agency is cooperating fully with criminal investigations, adding that it was critical that HUD agreed not to reinstate LAHSA’s suspension, so that it can continue to manage federal dollars until they’re handed off.

    Judge wanted more 'teeth' for the court

    Carter spent much of the hearing asking attorneys for the parties what power he would have to enforce the deal after signing. The proposed settlement lets him settle disputes and receive reports, but he said that left him looking over shoulders without the authority to actually enforce it.

    “I have no jurisdiction. I have no teeth,” he said.

    He read aloud from 2024 hearings in a related lawsuit, known as L.A. Alliance, where he warned that bills without supporting documents should not be paid. Essayli said that the proposed settlement would be binding “and we'll vigorously enforce it.”

    Myers said the deal gives the court oversight to ensure that the problems federal authorities flagged “don’t exist.”

    Carter asked to have the ability to hire an expert, at about $150 an hour paid by HUD, to help him understand the quarterly reports on implementing the deal that transfers federal roles from LAHSA to the county. Essayli agreed.

    How the case got here

    HUD suspended LAHSA from federal funds on June 11, citing alleged failures in the agency’s financial management and conflict-of-interest safeguards. The move put roughly $240 million in expected federal homelessness funding for the region in limbo and held up federal funding HUD had already awarded.

    LAHSA, which is overseen by the city and county’s elected officials, sued.

    In August, Carter blocked the suspension, writing that LAHSA and HUD had been in “a joint partnership in failure,” and ordering a competition for LAHSA's federal roles. He deferred the selection to the continuum of care — the body designated by federal law to make that choice.

    In October, the continuum chose the county for all four, over objections from L.A. Mayor Karen Bass and several City Council members who wanted the city to share control. The city then reached a tentative side deal giving it access to data on unhoused residents and a role placing people in city-funded housing.

    What happens next

    Carter said he expects to sign the proposed settlement on Monday.

    Myers said the deal lets the region “build a peaceful transition of power.”

    “We won,” Glass said on social media. “We’ll keep putting students first and supporting every teacher, every classified professional and every family.”

    All four incumbents are up by double-digit percentage points, Orange County election results show. The election follows last year’s recall of two conservative school board members.

    In a race for the Davis Unified school board, an anti-transgender candidate who once stripped down to a bikini at a school board meeting, lost decisively, according to unofficial election results. Beth Bourne, president of the Yolo County chapter of Moms For Liberty, trails incumbent Elizabeth Moon by 89 percentage points, results show.

    In Palo Alto — where issues over academics dominated the race — newcomers Avery Wang and Linda Henigin are ahead in unofficial results for two seats. John Craig, who ran in tandem with Wang, conceded on election night. Wang ran primarily on retaining academic rigor, especially in math. “It’s the beginning of a movement,” Wang told Palo Alto Online.

    Henigin ran on a platform of improving student well-being following a recent spate of student suicides.

    Elsewhere in the state, school board candidates in conservative strongholds such as Chino Valley and Temecula fared poorly in local school board races.

    In Temecula, school board President Joseph Komrosky trails challenger David Sola by 10 percentage points, results show. Sola has declared victory. Komrosky had voted to ban critical race theory in district schools and attempted to ban teaching materials that mentioned slain gay rights icon Harvey Milk, drawing a sharp rebuke from Gov. Gavin Newsom.

    Komrosky’s apparent defeat was part of what The Press-Enterprise reported as “a seismic shift in local governance given recent elections that gave power to the Christian right.”

    In Chino Valley Unified in San Bernardino County, two conservative school board candidates are trailing far behind, results show. Chris Shaw, the husband of State Superintendent of Public Instruction candidate Sonja Shaw, trails Frank Gerdine by nearly 17 percentage points, while Meagan Lichthart is ahead of Shaun Smith, backed by Shaw, by 15 percentage points.

    Major service cuts at Metrolink, Southern California’s regional commuter rail service, are on hold for now thanks to a $20 million grant from the California State Transportation Agency. The Metrolink board of directors approved the agency’s $420 million budget on Friday.

    Why it matters: The previous budget proposal included slashing a third of weekday trains and 40% of weekend trains.

    Background: Metrolink staff have worked on this year’s budget since last September. The agency has pointed to slowing fare revenue, rising costs due to inflation and low ridership numbers for its budget troubles.

    Read on … for the latest on Metrolink’s budget.

    Major service cuts to Metrolink are on hold for now thanks to a $20 million grant from California’s State Transportation Agency. The Metrolink board of directors approved the agency’s $420 million budget on Friday.

    The previous budget proposal included slashing a third of weekday trains and 40% of weekend trains.

    “Thankfully, our customers were spared the disappointment and frustration of losing the service they rely on to travel the region for business and pleasure,” Tom Schamber, chief financial officer at Metrolink, said at the board meeting.

    How did we get here? 

    The Metrolink budget had been approved quarterly since June as staff worked out the annual budget.

    Metrolink staff have worked on this year’s budget since last September. The agency has pointed to slowing fare revenue, rising costs due to inflation and low ridership numbers for its budget troubles.

    “Fare box revenue ended the year $14 million under budget. This was sobering, and we realized that not only was fiscal [20]26 off, but our ridership expectations for fiscal year [20]27 would need to be recalibrated to this new baseline,” Schamber said.

    A majority of Metrolink’s budget is funded by Orange, Los Angeles, Riverside, San Bernardino and Ventura counties’ transportation agencies. For more than a year, Metrolink officials have been building a budget that member agencies, like the Orange County Transportation Authority and L.A. Metro, would approve.

    L.A. Metro and OCTA cut their subsidies to Metrolink by 3% and 10%, respectively.

    “The challenges ahead of us were becoming more evident,” Schamber said at Friday’s board meeting. “In addition to disappointing fare revenue and funding limitations, we must absorb inevitable cost increases in several of our largest contracts.”

    What we know about the grant

    The $20 million grant from the state comes with the expectation that Metrolink will retain the same service levels provided today, Schamber added.

    Metrolink CEO Darren M. Kettle said another expectation is that the agency must plan to maintain its services for the upcoming year.

    “We don't have a plan. We're working on a plan to make sure we have the funding to deliver the same level of service at a minimum,” Kettle said. “With respect to these conditions, based on what we know now, as of last evening, our staff is confident that Metrolink will be able to meet these conditions.”

    What’s next? 

    Kettle said staff got a head start on next fiscal year’s budget through the state grant application. Officials said the rail agency is also gearing up for the 2028 Olympic Games.

  • Transportation secretary says communications issue
    A Uniter Airlines plane on a tarmac near the terminal
    A United Airlines Boeing 787 Dreamliner sits on the tarmac earlier this year. Activity at Terminal 8 — United's main terminal — was disrupted Halloween morning due to a carbon monoxide leak.

    Topline:

    The Federal Aviation Administration grounded all flights nationwide Friday afternoon because of communications problems at regional air traffic control centers. The FAA notice said the ground stop was being imposed “due to extraordinary circumstances and for reasons of safety.” Transportation Secretary Sean Duffy said there is a communications issue affecting the 22 regional air traffic control centers that direct planes en route between airports nationwide. He said FAA technicians are investigating.

    What officials said: Secretary of Homeland Security Markwayne Mullin said there was no indication yet that “this was a nefarious attack against us. It’s just a telecommunications outage.” “Everybody’s safe. There’s no reason to be concerned about your loved ones if they’re flying,” Mullin said.

    The context: This is the first nationwide ground stop since January 2023 when a key FAA computer system malfunctioned. Before that the last time had been after the Sept. 11, 2001 terrorist attacks. Friday’s ground stop was different than the one after Sept. 11 because planes were not being told to land immediately and pilots likely were able to communicate with ground controllers at airports, Arroyo said.

    What's next: There is no timeline for restarting flights. Mullin said investigators will look at whether there is any link to the FAA’s nationwide rollout of a new artificial intelligence system to help identify problems and reroute planes. But that system operates out of one location near Washington, D.C., and just sends recommendations to the air traffic control centers.

But that system operates out of one location near Washington, D.C., and just sends recommendations to the air traffic control centers.

    The government has been working to overhaul the outdated technology that air traffic controllers rely on since Congress approved $12.5 billion for the project last year. Miles of old copper wires have been replaced with fiber optic lines and old radio systems are gradually being replaced at airports across the country.

    But much work remains. Duffy has said that another $30 billion will be needed to complete the work, and the White House has begun lobbying Congress to approve it.

    The problem appeared similar to a regional air traffic control communication outage in September that snarled hundreds of flights across the Northeast, aviation safety expert Steve Arroyo said, except this time on a nationwide scale. It may be linked to the outdated technology used by air traffic controllers.

    “If you don’t have that ability, whether it’s because the old wires that they have are just run down or for whatever reason, you’ve got to stop airplanes on the ground,” said Arroyo, who is a former United Airlines pilot. “And not put them in the air where you’re going to risk not being able to communicate with them.”

    Friday’s ground stop was different than the one after Sept. 11 because planes were not being told to land immediately and pilots likely were able to communicate with ground controllers at airports, Arroyo said.
