A federal appeals court temporarily halted a judge's ruling that had blocked the Trump administration from deploying members of the California National Guard in L.A.

How did Trump send in National Guard Troops and Marines to L.A.? An explainer of presidential authority and the limits of military law enforcement.

What the judge rules, and the likely appeals that follow, may alter decades of understanding about the roles of governors and the White House in quelling domestic unrest.

Gov. Gavin Newsom posted on social media that "Commandeering a state's National Guard without consulting the Governor of that state is illegal and immoral."

An escalating clash pits a Republican president looking to fulfill his mass deportation goals against a Democratic governor with White House aspirations hoping to mobilize opposition.

A federal judge will hold a hearing on Thursday over California’s request to block the Trump Administration from using troops in Los Angeles to quell unrest sparked by Immigration and Customs Enforcement (ICE) raids as part of the President’s mass deportation effort.

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

A federal court hearing is scheduled for Thursday challenging Trump's use of the National Guard and Marines to support immigration raids in Los Angeles. California leaders warn that the military intervention is the onset of a much broader effort by Trump to overturn norms at the heart of America's political system.

California Lieutenant Gov. Eleni Kounalakis suggested President Donald Trump was responsible for escalating the anti-ICE riots in Los Angeles over the weekend.
