San Francisco — A federal court hearing is scheduled for Thursday on whether the Trump administration can use the National Guard and Marines to assist with immigration raids in Los Angeles.

Protests over the immigration crackdown have been held in major cities throughout the U.S. in recent days. Los Angeles Mayor Karen Bass joined fellow Democratic mayors across the country Wednesday in calling for an end to the raids, which she called a provocation by the White House.

Demonstrations in solidarity with Los Angeles protests against immigration raids have spread throughout the country.

President Donald Trump ordered the deployment of 2,000 National Guards troops to quell immigration protests in Los Angeles, overriding California Gov. Gavin Newsom’s objections in a rare move.

About 500 of the National Guard troops deployed to the Los Angeles protests have been trained to accompany agents on immigration operations, the commander in charge said Wednesday.
