Newsom filed a lawsuit Monday in response to Trump ordering the deployment of roughly 4,000 National Guard members to Los Angeles following protests over his stepped-up enforcement of immigration laws. They were originally called in to protect federal buildings, and the president later ordered the deployment of 700 Marines.

California has challenged the administration's move to call up the National Guard over the objections of Governor Gavin Newsom.

The state of California is seeking to stop the president from sending National Guard troops without the governor’s approval.
