A federal appeals court in San Francisco is set to hear arguments on whether the Trump administration should return control of National Guard troops to California.

A federal appeals court will hear arguments on Tuesday on President Donald Trump's authority to deploy the National Guard and Marines to Los Angeles amid protests and civil unrest, days after a lower court ruled that the president unlawfully called the National Guard into service.

Gov. Newsom's legal team calls President Trump's arguments for deploying troops to Los Angeles "terrifying." The 9th Circuit Court of Appeals Tuesday is hearing the case.
