In the days before protests erupted in Los Angeles, the Trump administration stepped up its efforts to detain migrants — taking into custody those who arrived for routine check-ins while also conducting workplace raids that have sent waves of fear across Southern California and beyond.

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.

With the downtown facing an 8 p.m. curfew, the Los Angeles police began using tear gas and crowd-control munitions to break up protests after issuing a dispersal order.

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 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.

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

The downtown curfew encircles the downtown civic center, including City Hall, the main county criminal courthouse, LAPD headquarters and federal buildings.

President Donald Trump sent in troops, but demonstrators have largely come face to face with local police instead
