Gov. Tony Evers announced Monday that Wisconsin has signed on to an effort to support the state of Minnesota’s lawsuit seeking to challenge the presence of Immigration and Customs Enforcement and Border Patrol agents in the Twin Cities area. 

Minnesota filed its lawsuit after the federal government sent about 3,000 federal agents into the region and an ICE agent shot and killed Renee Good Jan. 7. On Saturday, agents shot and killed Alex Pretti. Minnesota is seeking a temporary restraining order against the federal government’s actions.

Late last week, Wisconsin joined Arizona, Colorado, Connecticut, District Of Columbia, Delaware, Hawai‘i, Illinois, Maine, Maryland, Massachusetts, Michigan, New Jersey, New Mexico, New York, Nevada, Oregon, Vermont and Washington in filing an amicus brief supporting Minnesota’s case. 

“DHS has set in motion an extraordinary campaign of recklessness and disregard for norms of constitutional policing and the sanctity of life,” the brief states. “This has resulted in federal agents that have fatally shot one resident, seriously wounded others, tear gassed an infant and other children, attacked peaceful protestors, and systematically conducted illegal stops and arrests. When tragedy has struck and public outcry rung out, the response has been a promise to deliver more of the same. Indeed, just days ago, President Trump threatened to invoke the Insurrection Act, and it is reported that the Pentagon is preparing 1,500 troops to possibly deploy to Minnesota, reflecting the Administration’s desire to further escalate tensions and put the military into an unlawful domestic role.” 

The brief argues that the states have a “strong interest in ensuring that federal immigration enforcement is not used as an excuse to infringe the sovereignty of the States,” and that if allowed to continue unchecked in Minnesota, will likely repeat the pattern elsewhere. 

“Under the claimed auspices of carrying out immigration enforcement, the federal government has seriously undermined state and local authorities and made it impossible for the public to go about their day-to-day activities because they fear being stopped, tear gassed, or worse,” the brief states. “If left unchecked, the federal government will no doubt be emboldened to continue its unlawful conduct in Minnesota and to repeat it elsewhere.” 

Evers said in a statement that Wisconsin has a responsibility to stand up for its neighbor and work to prevent further damage. 

“Wisconsin stands with our neighbors across the river in Minnesota. American citizens are having their rights and freedoms violated and are being put in unsafe and life-threatening situations in their own communities,” Evers said. “Two have already lost their lives. It has to stop.” 

“In Minnesota and across our country, dangerous and unlawful actions at the hands of untrained individuals are sowing fear, division, and distrust,” Evers added. “This isn’t helping make our kids, families, and communities safer—in fact, it’s doing the opposite. It’s clearer than ever that this has nothing to do with public safety. And, as states, we have a responsibility to stand up and say no more.”
