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.

California Gov. Gavin Newsom is suing Trump in an attempt to block the deployment of federal troops in the city, which Newsom has called a “serious breach of state sovereignty.”
