Newsom plans to file suit against the Trump administration to roll back the National Guard deployment, which he called “an illegal act, an immoral act, an unconstitutional act.”

California officials on Monday said they would file a federal lawsuit over the mobilization of the National Guard during the weekend's massive immigration protests.

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.
