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.

Roughly 700 Marines from the Twentynine Palms base have been mobilized in response to protests and unrest in Los Angeles.

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.
