U.S. President Donald Trump can keep his deployment of National Guard troops in Los Angeles, according to a court ruling, as protests against immigration raids look set to enter their second week in the strongest backlash since his return to power in January.

Armed Marines arrived on the streets of Los Angeles Friday, part of a large deployment of troops ordered by Donald Trump that has raised the stakes between the US president and opponents claiming growing authoritarianism.

With migrant communities already living in fear amid the Trump administration's immigration crackdown, ICE raids in downtown Los Angeles sparked days of protests.

Thousands of demonstrators chanted “ICE out of L.A.” amid protests against immigration raids. A California challenge to Trump’s L.A. military deployment moves to a courtroom Thursday.

The power of the US military will be sharply on display this weekend – on two different coasts and in two very different ways.

California has challenged the administration's move to call up the National Guard over the objections of Governor Gavin Newsom.

ToplinePresident Donald Trump took credit Thursday for calming protests in Los Angeles, alleging his deployment of federal troops there stopped demonstrations from growing, while California Gov. Gavin Newsom has said the military presence actually inflamed protests—as the two long-time political nemeses have contradicting narratives of their roles in managing the demonstrations.

Former Capitol Police officer Harry Dunn said, "Trump thinks anything done in his name is OK. Jan. 6 was done in his name, so our officers don't matter."
