Live from NPR News in Washington, I'm Shay Stevens.

A manhunt continues for the assassin who killed conservative activist Charlie Kirk at Utah Valley University today.

President Trump is blaming the slang on political rhetoric from the left, and Pierre Stammer Keith has more.

In the video shot in the Oval Office, President Trump praised Kirk for his conservative activism and commitment to open debate.

Trump said what happened to Kirk is a direct consequence of people demonizing those they disagree with in hateful and despicable ways, and then turned his ire to the political left.

Radical left political violence has hurt too many innocent people and taken too many lives.

Tonight, I ask all Americans to commit themselves to the American values for which Charlie Kirk lived and died.

There have been recent cases of right-wing political violence as well, but Trump didn't mention those.

President Trump's takeover of Washington, D.C.

police expired today, but the National Guard and some federal agents remain in the city.

As NPR's Luke Garrett reports, the White House says the law enforcement surge netted more than 2,300 arrests, many involving immigration.

Since August 7th, federal authorities from the FBI, U.S.

Marshal Service, and others have arrested 2,310 people, seized 225 guns, and cleared 50 homeless encampments.

That's according to a White House official not authorized to share the data publicly.

D.C.

Mayor Muriel Bowser questions whether all these arrests were made in D.C.

I would say when I heard them, that seemed like it would have had to be greater than the district proper.

That's kind of my first gut reaction.

Despite multiple requests, the White House has not provided specific case numbers, charges, or names for those arrested.

The Trump administration says a revamped citizenship verification tool has checked over 33 million registered voters.

NPR's Jude Joffey Loff Block reports that there are still some unanswered questions about the tool's accuracy and data security.

SAVE is a federal data system that has long been used to verify immigration status.

In recent months, U.S.

citizenship and immigration services rapidly made several changes, including linking SAVE to Social Security Administration data.

Now the agency says SAVE can verify the citizenship of most U.S.-born citizens, too.

Some Republican-led states are running their voter rolls through SAVE, amounting to almost a sixth of all registered voters so far.

But some election officials from both parties are hesitating or refusing to use the tool, citing outstanding questions, including how the federal government can use the voter data that states upload.

FBI Director Cash Patel is being sued by three former employees, alleging they were fired on orders from the White House.

The lawsuit seeks reinstatement, back pay, and a ruling that the firings were illegal.

One plaintiff, Brian Driscoll, alleges Patel told him that his job stability depended on firing people involved in the prosecution of President Trump.

Driscoll is a former commander of the FBI's hostage rescue team.

He briefly served as acting FBI director when Christopher Wray resigned in January.

Scientists are celebrating the 10th anniversary of their ability to detect shockwaves from colliding black holes.

As NPR's Nell Greenfield Boyce reports, the discovery has allowed researchers to probe some of the most extreme events in the universe.

It was September 14th, 2015, when two massive detectors, one in Washington state and one in Louisiana, caught the distinctive signal of so-called gravitational waves.

Predicted by Albert Einstein almost a century earlier, these waves move through space after being created by cataclysmic events, in this case, two colliding black holes.

Since then, scientists have improved their detectors dramatically.

And now, in the journal Physical Review Letters, researchers describe the clearest signal yet.

It let them essentially watch two black holes growing as they merged into one, allowing them to verify a key theory about the growth of black holes that was put forth by physicist Stephen Hawking in 1971.
