U.S. President Donald Trump on Thursday threatened to use the Insurrection Act, which would allow him to deploy military forces, in Minnesota amid escalating tension over a deployment of federal agents in the state’s most populous city, which has become the focus of daily clashes.

“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.
