California Gov. Gavin Newsom said the state will sue to block the White House deploy hundreds of U.S. Marines to Los Angeles in response to protests over federal immigration raids, as he described the move as illegal and a “blatant abuse of power” by President Donald Trump and his officials.

President Donald Trump’s immigration agenda has met a groundswell of opposition in Los Angeles, the country’s second-largest city.

The description could become a rationale for invoking the 1807 Insurrection Act, which would give the president broad authority to use the military to deal with violence.
