Did President Trump send the U.S. military to Los Angeles earlier this week to safeguard the city from protesters? Or is this the start of something bigger — an unprecedented push by the president to carry out mass deportations with the help of armed troops?

The hearing comes after the 9th U.S. Circuit Court of Appeals granted a request by the administration last week to temporarily pause a lower court order that directed President Donald Trump to return control of the soldiers to the governor who filed a lawsuit over the deployment.

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.
