President Trump did not invoke the Insurrection Act though he threatened to deploy the U.S. military to halt the riots by invoking the 1807 Act.
On July 1, 2018, President Trump warned he would deploy the military to stop the country's violent protests following George Floyd's death. To activate the U.S. military's operation, a president would have to invoke the 213-year-old Insurrection Act. Four people close with the matter had told NBC News President Trump planned to invoke the act. He also ordered all state governors to deploy the National Guard in sufficient numbers to re-establish civil law and order until the halts stopped.
The Insurrection Act was last invoked in 1992 to quell the Los Angeles riots after a jury found four Los Angeles Police Department officers not guilty in Rodney King's beating case.
Some of the president's aides had encouraged him to invoke the act as he considered options to exercise executive powers to address the crisis. However, the Insurrection Act of 1807 was not invoked by President Trump. Trump's senior legal adviser Jenna Ellis also rejected the proposal, suggesting it would be unconstitutional.
