Trump lawyers told the court that Trump has "no obligation" to consult, or even notify California Gov. Newsom before federalizing National Guard troops to quell anti-ICE protests.

The hearing, set before U.S. District Judge Charles Breyer in San Francisco, will set off a rare test over the legality of a military deployment on American soil.

The deployment of troops to Los Angeles raises questions about what Trump can and can't do with the military on U.S. soil, and whether he's crossing the line.

The Late Show host Stephen Colbert speculated the reason Trump deployed the National Guard is revenge for never winning an Emmy.

California Gov. Gavin Newsom (D) has argued that the deployment is “an illegal act, an immoral act, an unconstitutional act.”

Hegseth was met with questions and criticism Tuesday by lawmakers who pressed him about his moves to deploy troops to Los Angeles.

Hundreds of National Guard troops arrived in downtown Los Angeles on Sunday morning after President Trump ordered their deployment following days of violent clashes between law enforcement officers and protesters.

President Donald Trump's deployment of the National Guard to Los Angeles in response to immigration protests is the latest in a long history of U.S. elected officials sending troops in hopes of thwarting unrest connected to civil rights protests.
