Oregon is joining a legal brief with 19 other states opposing President Donald Trump’s move to deploy the military in California to assist with immigration raids.

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 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.”

A federal judge said the White House has until noon Friday to give Gavin Newsom control of the National Guard in L.A.

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.

"If he can successfully militarize LA without significant political consequences, Baltimore is next," said Angela Angel of BLM PAC.
