Minneapolis live updates: DOJ launches investigation into Pretti killing, Deputy AG Blanche says

Trump administration border czar Tom Homan said in a press conference in Minneapolis on Thursday morning that "sanctuary cities are sanctuaries for criminals" and that he will now focus on regaining order by removing "threats from the community."

Homan added that he will be working to identify and remove undocumented immigrants that "pose a public safety threat and a national security threat."

"I didn't come here looking for photo ops and headlines," Homan said. "I come here looking for solutions."

Trump administration border czar Tom Homan will hold a press conference in Minneapolis on Thursday at 8 a.m. ET, the White House said in an advisory.

President Donald Trump dispatched Homan to Minnesota this week as part of a leadership shuffle.

On Wednesday, Minnesota Gov. Tim Walz visited the memorial for Alex Pretti telling ABC News Correspondent Matt Rivers, "I'm not so interested in shift in tone. We just need them out of here, and we need accountability for what's happened."

A newly emerged video appears to show Alex Pretti in a confrontation with federal agents 11 days before he was shot and killed in Minneapolis.

In the video, a man who appears to be Pretti and others on the scene are seen shouting at agents blocking an intersection in Minneapolis on Jan. 13. A man who looks like Pretti is then seen kicking a federal vehicle before agents get out, push him and tackle him to the ground. Agents then fire gas into the crowd.

The agents get up and the man appearing to be Pretti walks away, a gun visible on his waistband.

ABC News does not know what happened before this altercation.

The Department of Homeland Security told ABC News on Wednesday that Homeland Security Investigations is reviewing the video.

A new video appears to show Alex Pretti clashing with agents 11 days before his fatal shooting in Minneapolis.
