(AP) – President Donald Trump on Thursday threatened to invoke the Insurrection Act to justify deploying troops as protests against Immigration and Customs Enforcement persist in Minneapolis.

Trump made the threat to “quickly put an end to the travesty” after a federal officer shot a man in the leg while being attacked with a shovel and broom handle on Wednesday. The incident further heightened the sense of fear and anger radiating across the city a week after an immigration agent fatally shot a woman 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.
