“If the corrupt politicians of Minnesota don’t obey the law and stop the professional agitators and insurrectionists from attacking the Patriots of I.C.E., who are only trying to do their job, I will institute the INSURRECTION ACT,” Trump wrote in a Truth Social post.

Trump’s threat on social media came on the heels of the shooting by a U.S. immigration officer of a Venezuelan man fleeing a traffic stop in Minneapolis on Wednesday, one week after the fatal shooting of a U.S. citizen.

The U.S. Department of Homeland Security, which is overseeing Trump’s immigration crackdown, said that during Wednesday’s incident, two people attacked the federal officer with a broomstick and snow shovel as he wrestled with the Venezuelan, who the DHS said was in the U.S. illegally.

The Insurrection Act is a law authorising the president to deploy military forces on U.S. soil.
