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.

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.”

Over the years, Trump has threatened to intercede in the state’s long-running homeless crisis, vowed to withhold federal wildfire aid as political leverage in a dispute over water rights, called on police to shoot people robbing stores and warned residents “your children are in danger” because of illegal immigration.

Protests over President Trump's immigration enforcement raids and his mobilization of the Marines and National Guard in Los Angeles have spread to other major U.S. cities.

New Jersey activist and advocates drew parallels to Newark mayor's recent arrest by ICE agents outside detention facility.

LOS ANGELES (AP) — President Donald Trump’s use of troops to help carry out intensified immigration raids faces its biggest challenge yet on Thursday, when a federal judge is set to weigh a request from California Gov. Gavin Newsom to put an emergency stop to the practice.
