President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

President Donald Trump has deployed 4,000 National Guardsmen and 700 Marines to LA. But California Gov. Gavin Newsom and California Attorney General Rob Bonta are suing the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

National Guard members and Marines deployed to Los Angeles cannot perform law enforcement duties by law. That would change if Trump invokes the Insurrection Act.

The Pentagon’s deployment of about 700 Marines to Los Angeles to join the National Guard’s response to immigration protests follows weeks of rapid-fire developments as President Donald Trump pursues his top domestic priority for mass deportations.

Senators from both sides of the aisle took to responding over President Donald Trump's calling of the National Guard in Los Angeles.

U.S. District Judge Charles Breyer, a former Watergate prosecutor, will decide whether Trump had the legal authority to federalize 4,000 California National Guard troops.
