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

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.

The Trump administration faces a legal challenge to its deployment of the military to protests. Tensions flared after President Trump sent troops, and protests spread to other U.S. cities.

Homeland Security Secretary Kristi Noem pledged to carry on with the Trump administration’s immigration crackdown despite waves of unrest across the U.S.

An escalating clash pits a Republican president looking to fulfill his mass deportation goals against a Democratic governor with White House aspirations hoping to mobilize opposition.

Noem was in L.A. to address the ongoing demonstrations protesting President Donald Trump's immigration policies.

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.
