The lawsuit will seek to set aside the president’s order calling up troops in response to protests that spread over the weekend.

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.”

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.
