California Gov. Gavin Newsom said President Donald Trump is “pulling a military dragnet” across Los Angeles during a brief public address on Tuesday.

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

California Gov. Gavin Newsom (D) has argued that the deployment is “an illegal act, an immoral act, an unconstitutional act.”

LOS ANGELES (Reuters) -Hundreds of U.S. Marines arrived in Los Angeles overnight and more were expected on Tuesday under orders from President Donald Trump, who has also activated 4,000 National Guard troops to quell protests despite objections from California Governor Gavin Newsom and other local leaders.

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.
