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.

Anti-ICE protests continue in Los Angeles after the National Guard was deployed following immigration enforcement actions.

The last time the National Guard was activated without a governor’s permission was in 1965, when President Lyndon B. Johnson sent troops to protect a civil rights march in Alabama.
