President Donald Trump‘s announcement of the deployment of the National Guard in California to quell protests against U.S. Immigration and Customs Enforcement (ICE) actions has raised legal concerns.

Why It Matters

Federal immigration enforcement operations sparked protests across California for a second day in a row on Saturday. ICE carried out raids in Paramount, Los Angeles County, following similar actions at several locations throughout other parts of city on Friday.

Governor Gavin Newsom criticized the move, saying that local law enforcement was already mobilized and the presence of the National Guard was “purposefully inflammatory,” would “escalate tensions” and “erode public trust.”

What To Know

On Saturday, the White House ordered the deployment of the National Guard to Los Angeles under a provision called Title 10 to “temporarily protect ICE and other United States government personnel who are performing federal functions.”

The National Guard is a state-based military force that serves as both a state and federal reserve branch of the U.S. Army and Air Force.

It typically operates under state command and is funded by the state. However, in some cases, troops may be assigned to federal missions while still under state control, with funding provided by the central government.

The law referenced in Trump’s proclamation allows National Guard troops to be placed under federal command, and permits this under three conditions: if the U.S. is invaded or faces the threat of invasion; if there is a rebellion or imminent rebellion against federal authority; or if the president is unable to enforce federal laws using regular forces.
