The Insurrection Act is a federal law that allows the president to deploy the military and National Guard troops to suppress civil disorder, insurrection or rebellion. It was last used by President George H. W. Bush during the Los Angeles riots after the Rodney King verdict in April 1992.

Gov. Gavin Newsom and other leading California Democrats criticized President Trump’s deployment of National Guard soldiers in Los Angeles, calling it an unnecessary provocation.

California governor and federal officials traded blame after ICE raids and a violent protest rocked the L.A.-area city of Paramount.
