Gavin Newsom said he planned to file a lawsuit Monday against President Donald Trump in response to the administration’s extraordinary deployment of the National Guard to confront immigration protesters who took to the streets in Los Angeles.

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.

California Attorney General Rob Bonta says the state’s sovereignty was “trampled” by President Donald Trump when he ordered National Guard troops to the immigration protests in Los Angeles.
