Donald Trump threatened on Thursday to invoke the Insurrection Actin Minnesota in response to protests in Minneapolis against federal immigration enforcement operations, as Minnesota governor Tim Walz overnight urged demonstrators in Minneapolis to be peaceful amid escalating tensions.

In a post on Truth Social Thursday morning, Trump said he would institute the Insurrection Act and “quickly put an end to the travesty that is taking place” in Minnesota if the “corrupt politicians of Minnesota don’t obey the law and stop the professional agitators and insurrectionists from attacking the Patriots of ICE”.

Trump’s remarks came as overnight, Walz, a Democrat, urged people in Minneapolis overnight to protest peacefully after it was reported on Wednesday evening that a federal officer had shot a man in the leg during an immigration enforcement operation in north Minneapolis.

The incident sparked protests in Minneapolis on Wednesday night, as the city remains on edge just one week after a federal immigration officer there shot and killed Renee Nicole Good.

“State investigators have been on the scene in North Minneapolis” Walz wrote on X overnight. “I know you’re angry. I’m angry. What Donald Trump wants is violence in the streets. But Minnesota will remain an island of decency, of justice, of community, and of peace. Don’t give him what he wants.”

The Guardian reported on Wednesday night that several hundred protesters gathered at the scene of the shooting on Wednesday night. At a news conference later, Minneapolis police chief Brian O’Hara said that protesters had been “engaging in unlawful behavior” and urged people to leave the area.

The Department of Homeland Security has said that the shooting occurred on Wednesday as “federal law enforcement officers were conducting a targeted traffic stop in Minneapolis of an illegal alien from Venezuela”. DHS alleged that the man resisted and attacked an officer, and said that two other individuals emerged from a “nearby apartment and also attacked” the officer, who, the department said “fired a defensive shot to defend his life”. The federal government’s account could not immediately be verified.

The city of Minneapolis has said that the man who was shot was taken to a local hospital with “apparent non-life-threatening injuries”.

On Wednesday evening, Walz delivered remarks on the ongoing federal presence in Minnesota, in which he said that “news reports simply don’t do justice to the level of chaos and disruption and trauma the federal government is raining down upon our communities.”

Walz said that between 2,000 and 3,000 armed federal agents had been deployed across the state and claimed that the ICE agents, who he described as “armed”, “masked” and “undertrained” were “going door to door ordering people to point out where their neighbors of color live”.

“They’re pulling over people indiscriminately, including US citizens, and demanding to see their papers” Walz said.

“Just plain grabbing Minnesotans and shoving them into unmarked vans, kidnapping innocent people with no warning and no due process” he added.

“Let’s be very, very clear” Walz said. “This long ago stopped being a matter of immigration enforcement. Instead, it’s a campaign of organized brutality against the people of Minnesota by our own federal government.”

During his remarks, Walz called on Trump and Kristi Noem, the homeland security secretary, to “end this occupation”.

“You’ve done enough,” he said.

Addressing Minnesotans, Walz said: “We can, we must protest loudly, urgently, but also peacefully.

“Indeed, as hard as we will fight in the courts and at the ballot box, we cannot and will not let violence prevail” he said. “You’re angry, I’m angry, angry is not a strong enough word, but we must remain peaceful.”

Walz’s address came amid reports that multiple federal prosecutors in Minnesota and Washington DC have resigned over the Trump administration’s handling of the investigation into the fatal shooting of Good. It was reported that six attorneys from the US attorney’s office in Minnesota quit on Tuesday over the justice department’s reluctance to investigate the ICE agent who fatally shot Good.
