Tensions flared in Los Angeles late Monday. On Tuesday, teams worked to scrub away, cover up or fade out protesters' graffiti.

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.

Monday's protests were largely calmer than Sunday's clashes. California officials insist that the 4,000 National Guards troops and 700 active duty Marines en route to L.A. are an unnecessary abuse of power by Trump.

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

President Donald Trump used a speech at Fort Bragg ostensibly to recognize the 250th anniversary of the U.S. Army to denounce the protesters in Los Angeles as a “foreign enemy” and declare his intention to “liberate” the city.
