A federal judge in San Francisco is weighing whether the Trump administration violated federal law by sending National Guard troops to accompany federal agents on immigration raids in Southern California.

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.

SAN FRANCISCO (AP) — A federal judge in San Francisco will consider evidence and hear arguments on whether the Trump administration violated federal law when it deployed National Guard soldiers and U.S. Marines to Los Angeles following protests over immigration raids this summer.

Trump announced plans on Monday to send 800 National Guard troops to Washington D.C., as his California guard deployment is on trial.

Gov. Gavin Newsom alleges the Trump administration broke a 19th Century law called the Posse Comitatus Act when it deployed military units to Los Angeles in June.

A federal judge heard arguments this week on whether military troops deployed this summer by the Trump administration to Los Angeles violated a federal law that bars troops from conducting law enforcement duties within the country.

In New Mexico’s most populous city, National Guard troops are listening to the police dispatch calls, monitoring traffic cameras and helping to secure crime scene perimeters, tasks not usually part of the job.
