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.

A high-stakes trial began Monday in a California courtroom over whether the Trump administration violated federal law when it deployed thousands of National Guard troops and United States Marines to Los Angeles following protests over immigration raids in June.
