SAN FRANCISCO (AP) — A federal judge in San Francisco is weighing whether the Trump administration violated federal law by sending National Guard troops to accompany immigration agents on raids in Southern California. A three-day trial on the matter concluded Wednesday.

A federal judge in San Francisco seemed unconvinced after a three-day trial that the continued deployment of federalized members of California’s National Guard — who were originally deployed to Los Angeles in response to protests against President Donald Trump’s immigration agenda — is lawful.

Defense Secretary Pete Hegseth said troops will not get involved in law enforcement but would be “proactive” if they saw something illegal happening.

The 800 soldiers, in round-the-clock shifts of 100 to 200, will support Washington police and federal law enforcement officers.

National Guard troops have begun 24-hour operations around Washington, D.C., as of Thursday morning, according to a Department of Defense official. It's part of President Donald Trump's plan to address crime in Washington by taking over the city's police department and deploying the National Guard troops.
