President Donald Trump said in a social media post that Minneapolis Mayor Jacob Frey is "playing with fire" after Frey said the city will not enforce federal immigration laws.

"Surprisingly, Mayor Jacob Frey just stated that, 'Minneapolis does not, and will not, enforce Federal Immigration Laws.' This is after having had a very good conversation with him," Trump wrote on social media. "Could somebody in his inner sanctum please explain that this statement is a very serious violation of the Law, and that he is PLAYING WITH FIRE!"

Frey said on social media on Monday that in his meeting with border czar Tom Homan, he "reiterated that my main ask is for Operation Metro Surge to end as quickly as possible."

"I shared with Mr. Homan the serious negative impacts this operation has had on Minneapolis and surrounding communities, as well as the strain it has placed on our local police officers," Frey said. "I also made it clear that Minneapolis does not and will not enforce federal immigration laws, and that we will remain focused on keeping our neighbors and streets safe. City leaders will continue to stay in conversation with Mr. Homan and his team."

Top White House adviser Stephen Miller said in a statement to ABC News that Trump administration officials are "evaluating" why Customs and Border Protection agents in Minneapolis “may not have been following” protocol leading up to the fatal shooting of Alex Pretti over the weekend.

Miller's statement comes as the administration is grappling with the fallout from the Minneapolis shooting -- and amid finger-pointing playing out from various officials behind the scenes.

In the immediate aftermath of the shooting, Miller described Pretti as a "domestic terrorist" in a post on X, language which was echoed by DHS Secretary Kristi Noem.

But Tuesday night, Miller provided this statement to ABC News, appearing to question the actions of Customs and Border Patrol and suggesting that agency was to blame for those initial assessments.

"The initial statement from DHS was based on reports from CBP on the ground. Additionally, the White House provided clear guidance to DHS that the extra personnel that had been sent to Minnesota for force protection should be used for conducting fugitive operations to create a physical barrier between the arrest teams and the disruptors. We are evaluating why the CBP team may not have been following that protocol."

White House border czar Tom Homan said his meetings with Minnesota Gov. Tim Walz and Minneapolis Mayor Jacob Frey on Tuesday were "a productive starting point."

"We all agree that we need to support our law enforcement officers and get criminals off the streets," Homan said in a post on X. "While we don’t agree on everything, these meetings were a productive starting point and I look forward to more conversations with key stakeholders in the days ahead."

Homan said that they discussed "the issues on the ground" in the state and added that President Donald Trump "has been clear: he wants American cities to be safe and secure for law-abiding residents -- and they will be."

A Department of Homeland Security report sent to Congress and obtained by ABC News says that two federal officers discharged their firearms during the shooting of Alex Pretti on Saturday in Minneapolis and does not say that Pretti attempted to reach for his weapon, based on a preliminary review of bodycam footage.
