Under the Insurrection Act of 1807, the president has the authority to use the National Guard and military in order to combat “unlawful obstruction or rebellion” within U.S. borders. The act was last invoked in 1992 by George H.W. Bush to quell the Los Angeles riots, and was also used by Eisenhower in 1957 to enforce school desegregation in the south.
