MINNEAPOLIS — President Donald Trump on Thursday threatened to invoke the Insurrection Act and deploy troops to quell persistent protests against the federal officers sent to Minneapolis to enforce his administration's massive immigration crackdown. The threat comes a day after a man was shot and wounded by an immigration officer who had been attacked with a shovel and broom handle. That shooting further heightened the fear and anger that has radiated across the city since an Immigration and Customs Enforcement agent fatally shot Renee Good in the head. Trump has repeatedly threatened to invoke the rarely used federal law to deploy the U.S. military or federalize the National Guard for domestic law enforcement, over the objections of state governors. “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, which many Presidents have done before me, and quickly put an end to the travesty that is taking place i
