The Trump administration faces a legal challenge to its deployment of the military to protests. Tensions flared after President Trump sent troops, and protests spread to other U.S. cities.

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Some polls suggest Trump's clashes with Elon Musk and aggressive response to immigration protests in Los Angeles have not weakened his standing.

The military parade coincides with President Donald Trump’s birthday, but faces opposition from planned protests, which organizers are dubbing a “national day of defiance.”

Trump deployed 4,000 National Guardsmen and 700 Marines to LA against the wishes of Newsom and Bass. Newsom sued the Trump administration, saying they unlawfully "trampled over" California’s sovereignty when they federalized the California National Guard.

“Multiple groups continue to congregate on 1st St between Spring and Alameda. Those groups are being addressed and mass arrests are being initiated. Curfew is in effect,” read a post on the LAPD’s social media, sent at 9:09p.m local time on Tuesday night.

Trump ordered California National Guard troops to Los Angeles in response to violent demonstrations against immigration enforcement.
