Marines have moved into Los Angeles to guard a federal building after a week of protests against immigration raids, while communities across the country are preparing for demonstrations against President Donald Trump’s polices this weekend.

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.

Tensions escalated after President Donald Trump called up the National Guard over the objections of state and city leaders.

Protesters across Southern California and the country took to the streets for ‘No Kings’ demonstrations against President Trump and the $45-million celebration of the U.S. Army’s 250th birthday, which coincides with Trump’s 79th.

Elizabeth Mendoza watched nervously as demonstrators protesting President Donald Trump’s immigration raids and policies clashed with police outside of her Compton restaurant, Restaurante Y Pupuseria La Ceiba.

The development comes a day after an appeals court temporarily blocked a judge’s order that directed President Trump to return control of the California National Guard.

The bill would enable community raids, targeted removals and widespread detention camps that sweep up U.S. citizens and the undocumented alike.

Customs and Border Patrol confirmed it is providing "aerial support" to law enforcement efforts during the protests.
