President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

President Donald Trump has deployed 4,000 National Guardsmen and 700 Marines to LA. But California Gov. Gavin Newsom and California Attorney General Rob Bonta are suing the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

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

Military-style vehicles and National Guards troops have blocked a portion of 4th Street in front of the Ronald Reagan Federal Building and Courthouse.

On June 8, President Donald Trump praised the California National Guard for its response to Los Angeles immigration enforcement protests.

Protests in Los Angeles appeared to quiet overnight, but new ones are popping up in other cities. Trump has deployed more than 4,000 National Guard troops and 700 Marines to the protests.

Los Angeles leaders set a downtown curfew Tuesday on the fifth day of protests against President Donald Trump's immigration crackdown as his use of the National Guard escalated and the governor accused him of drawing a “military dragnet” across the nation's second largest city.
