Police in Louisville, Kentucky, have arrested a suspect in a fatal shooting at a protest over the death of Breonna Taylor in Jefferson Square Park on Saturday night, per the Wall Street Journal.

What's new: Steven Nelson Lopez was charged with murder and wanton endangerment following the death of 27-year-old photographer Tyler Charles Gerth, per AP, which reports authorities saying the suspect "had taken part in demonstrations but was disruptive and had been asked by other protesters to leave."

  • Homicide investigators have interviewed the suspect, who's being treated in hospital for a gunfire injury to the leg after bystanders shot back, AP reports.

Zoom in: Video from the scene shows a man at the park's edge firing several shots, forcing protesters to scramble for cover. Louisville Metro Police Department said in a statement that Jefferson County Sheriff’s Department personnel "performed life-saving measures" on Gerth, but he died at the scene.

What they're saying: Mayor Greg Fischer tweeted: "I am deeply saddened by the violence that erupted in Jefferson Square Park tonight, where those who have been voicing their concerns have been gathered. It is a tragedy that this area of peaceful protest is now a crime scene."

The big picture: The March 13 death of Taylor, a 26-year-old African American emergency medical technician, prompted protests across Louisville. Her killing has since become a focal point of the Black Lives Matter protests.

  • Louisville police officer Brett Hankison was fired last Tuesday for "blindly" firing 10 bullets into Taylor's apartment, the police department announced.
  • The Justice Department is investigating Taylor's shooting.

Four men have been charged with destruction of federal property for allegedly trying to tear down the Andrew Jackson statue outside the White House this week, the Department of Justice said in a statement on Saturday night.

Driving the news: The announcement came hours after President Trump retweeted images of 15 people the U.S. Park Police said they and the FBI Washington Field Office's Violent Crimes Task Force were seeking to identify for "vandalizing" the statue and "other related crimes."

Mike Pence explains why he refuses to say "Black lives matter"

Vice President Mike Pence told CBS News' "Face the Nation" on Sunday that he won't say the words "Black lives matter" because he believes the leadership of the BLM movement is pushing a "radical-left agenda."

Why it matters: 67% of the American public say they support the Black Lives Matter movement in the wake of mass protests over George Floyd's killing, with 38% of U.S. adults saying they strongly support it, according to Pew. Yet the words "Black lives matter" have remained politically sensitive for many Republicans, who instead choose to use the phrase "all lives matter."

The latest: Trump appeared to have deleted the tweet around 11am ET Sunday, about three hours after posting it. White House spokesperson Judd Deere said in a statement: “President Trump is a big fan of The Villages. He did not hear the one statement made on the video. What he did see was tremendous enthusiasm from his many supporters.”
