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.

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.

Attorneys for Gov. Gavin Newsom headed back to court Monday over President Donald Trump ’s use of the California National Guard to subdue protests in Los Angeles, a tactic the White House is now repeating in the nation’s capital in what’s it’s calling a crime crackdown.
