Almost 5,000 National Guard troops and Marines have been assigned to Los Angeles — drawing stiff rebukes from state officials.

In announcing the lawsuit, Attorney General Rob Bonta called the president's move to federalize the National Guard an "infringement" on state sovereignty.

California sued the Trump administration on Monday over its decision to send in National Guard troops in response to protests over immigration enforcement, calling it an unconstitutional use of executive power that usurped the state’s authority.
