San Bernardino shooting makes for hot politics on Sunday morning talk shows

On today's Sunday morning chat shows, the number one topic was the mass shooting in San Bernardino — its connection to terrorism around the world and its impact on the 2016 presidential race.

On NBC's "Meet The Press," attorney general Loretta Lynch told host Chuck Todd that the focus of the FBI's investigation,  is what led Syed Farook and Tashfeen Malik "to pick up guns and become murderers. ... We are looking at everything we can find out about how these two killers live. How they grew up. Where they grew up. Where they met."

Lynch wouldn't divulge information about whether female shooter Malik might have been radicalized in Saudi Arabia.

Lynch also emphasized the evolving nature of terrorism both in the United States and abroad.

"We have come from the time of the large-scale, planned, Al Qaeda-style attacks to the encouragement of lone wolves. … We have been watching this threat evolve for some time. Because we, in fact, have been successful at stopping a number of plots, the threat has evolved."

Presidential candidates Hillary Clinton and Jeb Bush were the guests on ABC's "This Week." When asked by host George Stephanopoulos whether the United States was winning the war on ISIS, Clinton said, "We're not winning but it's too soon to say that we are doing everything we need to do. … We have to fight them in the air. We have to fight them on ground and we have to fight on the Internet."

Clinton was also asked why she's reluctant to say we're fighting radical Islam. "The problem is that that sounds like we are declaring war against a religion," Clinton said. "It helps to create this clash of civilizations that is actually a recruiting tool for ISIS and other radical jihadists who use this as a way of saying we're in a war against the West. You must join us. If you are a Muslim, you must join us. No. If you're a law-abiding, peace-loving Muslim, you need to be with us against those who are distorting Islam."

On CBS's "Face The Nation," Republican presidential frontrunner Donald Trump took a different tack.

When asked how to stop an attack with "no red flags" like this recent one, he said, "I think there are red flags. A lot of people knew what was going on in that house or that apartment. And people were not wanting to call because they thought it would be inappropriate to call. … So everybody wants to be politically correct and that's part of the problem that we have with our country."

Trump later said, "We are having a problem with the radicals in the Muslim group, let's not kid ourselves. And you can say it or you don't have to say it … You have people that have to be tracked. If they're Muslims, they're Muslims."

On "Fox News Sunday," presidential candidate Ben Carson, whose standing in the polls has fallen in the wake of the recent violence in Paris and San Bernardino, was asked how to fight homegrown terrorists.

"You need to recognize that there is no magic bullet," Carson said. "First of all, we have to teach everyone the importance of vigilance. And not being afraid to report something. ... I think the other thing that we are going to have to do is do a much better job of monitoring the Internet. And the things that cause people to be radicalized."
