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.

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