President Donald Trump's deployment of the National Guard to Los Angeles in response to immigration protests is the latest in a long history of U.S. elected officials sending troops in hopes of thwarting unrest connected to civil rights protests.

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

White House Press Secretary Karoline Leavitt said President Trump called in the National Guard with the expectation that it would "hopefully prevent and deter some of this violence.”
