Minneapolis ICE shooting live updates: Trump vows 'day of reckoning & retribution’ for Minnesota Democrats

In response to the lawsuit filed against the Department of Homeland Security over its federal deployment to Minnesota, the agency said Minnesota Attorney General Keith Ellison is "prioritizing politics over public safety."

"Sanctuary politicians like Ellison are the EXACT reason that DHS surged to Minnesota in the first place," DHS spokesperson Tricia McLaughlin said in a statement. "If he, Tim Walz, or Jacob Frey had just done their sworn duty to protect the people of Minnesota they are supposed to serve to root out fraud and get criminals off the street -- if they had worked with us to do it -- we wouldn’t be having this conversation in the first place."

"President Trump's job is to protect the American people and enforce the law -- no matter who your mayor, governor, or state attorney general is," she continued. "That's what the Trump administration is doing; we have the Constitution on our side on this, and we look forward to proving that in court."

The state of Minnesota and the cities of Minneapolis and Saint Paul have filed a lawsuit against the Department of Homeland Security to end the "unlawful, unprecedented surge of the federal law enforcement agents into Minnesota," Minnesota Attorney General Keith Ellison said at a news conference on Monday.

"Because this has to stop," Ellison said, standing alongside Minneapolis Mayor Jacob Frey and Saint Paul Mayor Kaohly Her. "We allege that the obvious targeting of Minnesota for our diversity, for our democracy and our differences of opinion with the federal government, is a violation of the Constitution and federal law."

The suit claims the surge amounts to a "federal invasion" to conduct unconstitutional stops and arrests at sensitive locations, including schools and hospitals, "all under the guise of lawful immigration enforcement."

"These poorly trained, aggressive and armed agents of the federal state have terrorized Minnesota with widespread unlawful conduct," Ellison said at the news conference.

The complaint alleges DHS is violating the 10th Amendment by its actions and follows a pattern of the Trump administration targeting Democrat-led cities.

The complaint also alleges that the administration is not using targeted enforcement and instead have been "conducting raids at job sites and businesses, detaining and deporting individuals while they perform essential work that directly benefits Plaintiffs’ communities."

"DHS agents also appear to be conducting general sweeps and detaining people within their path based on their race and ethnicity," the complaint said.

The complaint also alleges that businesses and schools in Minneapolis have been hurt by the federal surge, and the state claims DHS violated state law by staging immigration enforcement operations on state property.

The lawsuit asks a judge to preliminarily bar DHS from arresting individuals unless there’s "probably cause" to believe they have committed a crime. The suit also asks to prevent DHS from threatening physical force and brandishing weapons.

Notably, the lawsuit aims to prevent federal agents from "pointing firearms at individuals who are not posing an immediate threat of death or seriously bodily injury to another person."

Minnesota Gov. Tim Walz and his wife Gwen visited Renee Good's memorial in Minneapolis on Monday. The site is covered in flowers and signs, with one reading, "SHE WAS GOOD."

Last week Walz called on the Trump administration to "leave Minnesota alone" in the wake of the deadly ICE shooting. He asked to "de-escalate," allow Minnesotans to grieve, and "allow this investigation to be played out by the rule of law."

He said he believes the nation may be looking to Minnesota to "hold the line on democracy, to hold the line on decency, to hold the line on accountability."

"Don't give in to allowing them to bring more folks in here. Don't allow them to expand this somewhere else," Walz said. "Rise up. Wrap your arms around your neighbors. Peacefully express your First Amendment, your constitutional rights, and let's start healing."

The Department of Homeland Security plans to send "hundreds" of additional federal officers to Minnesota, Secretary Kristi Noem said on Sunday.

Additional officers were expected to arrive on Sunday and Monday, the secretary said in an interview that aired Sunday on Fox News.

"They'll arrive, there'll be hundreds more in order to allow our ICE and our Border Patrol individuals that are working in Minneapolis to do so safely," Noem said.

She added, "We're going to continue to, if they conduct violent activities against law enforcement, if they impede our operations, that's a crime, and we will hold them accountable to those consequences."
