U.S. President Donald Trump on Thursday threatened to invoke the 19th-century Insurrection Act, which would allow the deployment of the military within the country. The warning came as protests spread across Minnesota following the shooting of a man by federal agents on Wednesday and the earlier death of a woman last week. Demonstrators in the Democrat-leaning northern cities have been protesting against violence linked to the Trump administration’s extensive immigration enforcement operations.

Trump reiterated his threat on social media, saying he would use the Insurrection Act if Minnesota’s politicians failed to uphold the law and prevent attacks on Immigration and Customs Enforcement officers. He expressed frustration over court obstacles to deploying the National Guard and over the ongoing protests, signaling a tougher stance in advancing his anti-immigration agenda.

Minnesota’s Democratic Governor Tim Walz sharply criticized the Trump administration, accusing federal agents of conducting a “brutal campaign” against residents. In a video message, he cited incidents of home raids, mistreatment of pregnant women, and the killing of 37-year-old Renny Good. Walz urged peaceful demonstrations and called on Trump and Homeland Security Secretary Kristi Noem to end what he described as an occupation.
