The Brief

The Los Angeles Unified School District is weighing the future of its artificial turf and natural grass athletic fields. The district is in the midst of a study and collecting feedback from parents, students, staff and other stakeholders.

The outcome of the study, expected this summer, will inform the immediate replacement of seven deteriorated high school athletic fields and future projects.

The vast majority of the district’s turf, from front lawns to baseball fields, is natural grass, Krisztina Tokes, LAUSD’s chief of facilities, told LAist.

The percentage of synthetic turf increases if you isolate the district’s athletic fields — about 20% of the district’s athletic fields are synthetic turf and about 80% are natural grass. The concentration is highest in high schools’ combination soccer/football fields, 40% of which are synthetic.

“Synthetic turf was used at many of those school sites where we anticipated there would be very high use,” Tokes said. For some, the district shared the fields with city and youth sports programs.

Synthetic turf has a higher upfront cost than natural grass but requires less maintenance and water.

In recent years, researchers have raised concerns about the artificial turf’s impact on children’s health and the environment— for example, artificial turf can get hot enough to burn skin.

About a decade ago, LAUSD had to replace seven turf fields at the cost of $8.8 million because of defective materials, including plastic pellets that melted in the heat. The district later recovered $3.6 million from contractors associated with the fields, according to a report from the LAUSD inspector general.

Why this process is starting now

The study is the result of a unanimously adopted November 2025 board resolution that also prohibited the installation of artificial turf at early education centers, elementary and middle schools.

“No 4-year-old, no elementary student should be playing on surfaces hot enough to burn their skin or expose our children to chemicals,” said Rocío Rivas, the board’s vice president, during the meeting.

Student board member Jerry Yang said his peers wrote to him with concerns about artificial turf.

“In a dense, urban city like Los Angeles, where the amount of green space is often a reflection of a community's income level, it is all the more important that we switch away from artificial turf,” Yang said.

Speakers during public comment also called on the district to move away from synthetic turf.

The study will consider four key topics: playability, health and safety, environmental impact and cost and maintenance. The district has also brought on consultants LPA and Core America to help evaluate the fields’ environmental impact, health and safety.

LAUSD isn't the only district weighing the future of its athletic fields.

The Santa Monica-Malibu Unified School District recently completed a study that found synthetic turf increases field availability and saves water but that the findings about health and safety are less clear.

Here’s how to weigh in

The district is hosting a series of hybrid meetings and is inviting people to complete an online survey to collect feedback.

Monday's arraignment of 31-year old Cole Tomas Allen, a California man who is charged with attempting to assassinate President Donald Trump over the weekend, opened legal proceedings that many extremism experts will be watching closely.

Allen, a high school tutor with a background in mechanical engineering and computer science, allegedly attempted to storm the annual White House Correspondents Association Dinner on Saturday night, where Trump and other high-level administration officials were gathered with the Washington press corps. He was stopped by federal law enforcement officers before getting close to his presumed targets.

According to a White House official, Allen's sister told the Secret Service and local law enforcement that her brother was known to make "radical" statements. The official was not authorized to speak publicly and NPR has not confirmed this with Allen's family members. But this characterization has puzzled some experts who track extremism, who say that it does not align with writings and social media activity that are believed to link to the defendant.

"You look at the social media profiles that have been attributed to this suspect and they're really not that radical," said Jared Holt, senior researcher at Open Measures, a company that tracks online threats and narratives. "Oftentimes it's like quite centrist, pretty moderate left wing, if anything."

An affidavit filed by an FBI agent in support of the charges claims that Allen sent an email to members of his family moments before initiating the attack. The email specifies some grievances against Trump administration officials and policies.

"I'm not the person raped in a detention camp. I'm not the fisherman executed without trial. I'm not a schoolkid blown up or a child starved or a teenage girl abused by the many criminals in this administration," the letter states. The letter appears to reference a range of issues from immigration detentions under the Trump administration, U.S. strikes on alleged drug boats in the Caribbean, the bombing of a girls' school in Iran and the Epstein scandal.

In an apparent reference to Trump, the letter also says "I am no longer willing to permit a pedophile, rapist, and traitor to coat my hands with his crimes."

But Holt and others say these views, however pointed some of the terminology may be, fall within a modern mainstream left. He and others say it is very unclear what may have tipped the individual from such widely held views into an alleged violent plot.

"That's part of what's troubling, is when you start to have people who are kind of seemingly normal, law-abiding members of society feeling like violence is the solution," said Cynthia Miller-Idriss, founding director and chief vision officer at the Polarization and Extremism Research and Innovation Lab, or PERIL, at American University.

"I think there's a little bit of nihilism reflected here," Miller-Idriss said. "This idea that there is no more solution, violence is the answer, nothing else is going to change, nothing else is going to be effective."

The alleged assassination attempt is the latest high-profile data point in a growing environment of political violence in the U.S. over the last decade. While most of that is attributed to the far right, there is alarm about rising violence from the left. Even amidst this backdrop, however, Holt and Miller-Idriss both note that the weekend incident at the Washington Hilton hotel stands out.

For starters, Holt said he's seen no indication that the defendant was steeped in conspiratorial thinking. He said that more typically, people behind acts of violent extremism are nursing grievances fed by false narratives.

"If you were to just kind of randomly bump into one of these people on the street, you might get the sense that something was a little off," Holt said. "Whereas this seems -- just looking at, you know, this BlueSky profile that's been attributed to the suspect and this document that's been attributed to the suspect – I'm not getting that same kind of read."

In addition, Miller-Idriss said the defendant's presumed writings suggest that he felt personally responsible for not having taken action sooner against the administration. She said they do not appear intended to incite others to take similar action, or to spread a particular ideological message. The tone is one of "defeatism," Miller-Idriss said, which contrasts with a more typical pattern of political violence, particularly from the far right.

"I don't think you usually see the defeatism on the far right, [which is] more of a mobilization of martyrdom, of wanting attention, of wanting to launch a movement, to be a firestarter, that kind of thing," she said. "This is like a much more hopeless kind of language and rhetoric being used."

Holt said this tone is troubling, not simply because of how it may connect to the violence that Allen is alleged to have been planning. But also because it may signal that on the left, there may be a growing perception that the levers of democracy can no longer work to effect change.

"That is a bleak point for an individual to get to," Holt said. "But I also think that people are getting to that point now should be cause for reflection for people who work in politics or who work in advocacy, or whatever it may be, that [with] the many problems that we're up against today, there is a subset of the American population that's losing hope and is having a hard time imagining a way out of it."

A courtroom brawl between two of the tech industry's most powerful leaders, Tesla CEO Elon Musk and OpenAI CEO Sam Altman, is underway in Oakland, California, in a case that could transform one of the world's most important artificial intelligence companies.

"Ladies and gentlemen, we are here today because the defendants in this case stole a charity," Steve Molo, an attorney for Musk, said in his opening statement.

In his lawsuit, Musk has argued that Altman steered the company they cofounded a decade ago, ChatGPT creator OpenAI, away from its original mission as a nonprofit meant to develop advanced AI for the benefit of humanity and free of profit motives.

The case hinges on a decision early on by OpenAI's founders that they needed to create a for-profit entity to tap capital markets for funding on a scale necessary to build advanced AI. When discussions about who would run the for-profit business broke down in 2018, Musk left.

The following year, OpenAI launched a for-profit division, which has since ballooned in value; at the end of March, the company said it was worth $852 billion.

Now, Musk's lawyers are set to argue that Altman and others enriched themselves illegally through that for-profit conversion.

"They enriched themselves, they made themselves more powerful, and they breached the very basic principles on which the charity was founded," Molo said in court.

According to his suit, Musk is seeking a rollback of that change, and wants Altman, OpenAI President Greg Brockman and financial backer Microsoft to "disgorge" tens of billions of dollars in "ill-gotten gains" that have flowed from it.

Musk is also seeking Altman's ouster as a director of OpenAI's nonprofit board, and removal of both Altman and Brockman as officers of the for-profit company.

As part of his opening statement, Molo asked Musk to stand up, which he did — waving to the people in the courtroom.

"Everybody seems to know Mr. Musk and everybody seems to have an opinion about Mr. Musk," Molo said. But he reminded the jury that they took an oath to put their opinions aside, and thanked them for it. "The case isn't about Mr. Musk, it's about the defendants," he said.

He also filled the jury in on Musk's personal and business history; growing up in South Africa, immigrating to Canada and the United States, and giving a brief overview of Musk's companies including SpaceX, Tesla, and Neuralink.

Molo said that since college Musk has been concerned about what could happen when computers become smarter than people, and that over the course of the trial, his attorneys would call experts to testify about some of those risks, including the possibility that an AI could manipulate financial markets or disseminate misinformation, or that there could be a "concentration risk" caused by one powerful corporation or small group of people controlling a superpowerful AI.

"As AI became more advanced, Elon became more worried," Molo said, particularly about the idea that the government was not doing enough to curtail these risks. That led him to develop OpenAI along with Altman, Molo said, as a nonprofit intended to develop safer AI. "It wasn't a vehicle for people to get rich," Molo said. "And they wanted the technology to be open."

Musk poured about $38 million into the nonprofit over the course of about 5 years, Molo said. "Without Elon Musk there would be no OpenAI, pure and simple," he said.

Over time, Molo said, Musk and OpenAI's other leaders began discussing creating a for-profit entity to support the non-profit — he compared it to the way a museum store supports a museum.

Initially, Molo said, Musk would have majority control of the for-profit subsidiary, but eventually that would be diminished over time. But the partners could never come to an agreement, and Musk ended negotiations and later resigned from the OpenAI board.

The crux of his dispute with OpenAI, Molo said, is that OpenAI later did a $10 billion deal with Microsoft. At this point, Molo said, OpenAI "was no longer operating for the good of humanity as a whole. It was for profit operating for the good of the defendants."

OpenAI responds

OpenAI has long contended that Musk was onboard with the conversion to a for-profit company.

In an online statement published before the trial began, OpenAI has said Musk was involved in the discussions about converting part of the company to a nonprofit, and that in 2017, "We and Elon agreed that a for-profit was the next step for OpenAI to advance the mission."

OpenAI has also argued online that its mission has never changed. The for-profit entity is a subsidiary of the nonprofit OpenAI Foundation.

The company has framed the dispute as being more of a struggle over control than over the launch of a for-profit arm: Online, OpenAI has said that Musk wanted control of the for-profit company, but "we couldn't agree to terms on a for-profit with Elon because we felt it was against the mission for any individual to have absolute control over OpenAI."

"We're sad that it's come to this with someone whom we've deeply admired—someone who inspired us to aim higher, then told us we would fail, started a competitor, and then sued us when we started making meaningful progress towards OpenAI's mission without him," the OpenAI statement said.

In 2023, Musk launched his own AI company, xAI, now a subsidiary of his aerospace firm SpaceX.

And in court on Tuesday, OpenAI's lead counsel William Savitt hammered those points in his opening statement. "We're here because Mr. Musk didn't get his way at OpenAI," he said. And "because he's a competitor, he will do anything he can to attack OpenAI."

In 2017, he said, Musk wanted to turn OpenAI into a for-profit with himself at the helm. But, he said, "the other founders refused to turn the keys of artificial intelligence over to one person."

Musk sought to merge OpenAI with Tesla, he continued, but the other founders rejected that, too. "They didn't want to be part of a car company that Musk controlled," Savitt said.

"Most importantly," he continued, "One person having control wasn't consistent with OpenAI's mission."

After Musk left, Savitt said, Musk was furious that OpenAI succeeded without him: "Then he launched his own competitor. Then he launched lawsuits."

Savitt said that during the trial, OpenAI's attorneys will produce evidence to show that the OpenAI nonprofit foundation remains in control of the organization and that it's doing good work.

And they will argue that Musk's true interest in this suit is not OpenAI's nonprofit status. "What he cares about is Elon Musk being at the top," Savitt said.

The trial is expected to last around three weeks.

In addition to Musk, Altman is expected to testify, along with Brockman, Microsoft CEO Satya Nadella, and several key researchers and engineers involved in OpenAI's launch.

On his show Monday night, Kimmel responded to first lady Melania Trump's call for ABC to "take a stand" against him for a joke he made about her ahead of the White House Correspondents' Association Dinner. Two days after Kimmel's original segment aired, authorities subdued a heavily armed man who they say entered the event at the Washington Hilton ballroom in an attempt to target administration officials.

In a segment on Jimmy Kimmel Live! on Thursday, the comedian delivered a mock White House Correspondents' Dinner roast. "Look at Melania, so beautiful. Mrs. Trump, you have a glow like an expectant widow," Kimmel quipped.

In a post on X, the first lady called Kimmel's joke about her "hateful and violent."

On Monday, Kimmel told his audience, it "obviously was a joke about their age difference, and the look of joy we see on her face every time they're together." He said it was a "light roast" and was "not, by any stretch of the definition, a call to assassination. And they know that." Kimmel added that he's been very vocal for many years against gun violence.

Melania Trump didn't see it that way. "His monologue about my family isn't comedy- his words are corrosive and deepens the political sickness within America," she wrote on Twitter on Monday. "People like Kimmel shouldn't have the opportunity to enter our homes each evening to spread hate."

Mrs. Trump urged ABC, the network that airs Kimmel's weeknight show, to take action, asking "how many times will ABC's leadership enable Kimmel's atrocious behavior at the expense of our community?"

Hours later, President Trump took to social media to lend support to his wife. Trump wrote that Kimmel's comments went "beyond the pale" and that Jimmy Kimmel should be "immediately fired by Disney and ABC."

In September, Kimmel was taken off the air after a conservative backlash over comments Kimmel made in the aftermath of Turning Point USA co-founder Charlie Kirk's assassination. In his monologue, Kimmel said the "MAGA gang" was trying to score political points from the Kirk killing.

The FCC Chair Brendan Carr responded to the backlash by threatening ABC affiliates. "We can do this the easy way or the hard way," Carr said to podcaster Benny Johnson. "These companies can find ways to change conduct, to take action on Kimmel or, you know, there's going to be additional work for the FCC ahead."

Disney — which owns ABC — decided to suspend Kimmel's show. That decision sparked a furor over free speech and censorship. Kimmel's show returned six days later, and the host said, "it was never my intention to make light of the murder of a young man." Kimmel accepted why some people were upset with his remarks and said they had been "ill-timed,or unclear or maybe both."

Meanwhile, users on X have been responding to Melania Trump's post. Some appear to be supportive. Others point to the president's history of strongly worded, disparaging and racist remarks in posts about women and his political detractors such as Barack Obama.
