National Guard troops already have temporarily detained civilians in the Los Angeles protests over immigration raids.

On Tuesday, the X page for U.S. Immigration and Customs Enforcement (ICE) posted photos of California National Guardsmen on the scene of a detention being carried out by an ICE agent with the caption "Photos from today's ICE Los Angeles immigration enforcement operation."

Statesman on Wednesday that the city has been notified the Texas National Guard "will be prepared to assist the Texas Department of Public Safety if deemed necessary" for planned protests this weekend.

The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

The Guard’s arrival marks a potentially volatile phase in Trump’s push to ramp up deportations and in his contentious relationship with state and local authorities.

California officials, including Governor Gavin Newsom and LA Mayor Karen Bass, have described the move as "unnecessary".
