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.

The Los Angeles Police Department moved swiftly on Wednesday night to quell disorder stemming from anti-deportation protests, charging crowds on horses and firing “less lethal” munitions to clear protesters.

The Marines are expected to be serving alongside National Guard troops within the next 48 hours, according to the U.S. Northern Command.

At least a dozen groups are planning anti-Trump protests in the Los Angeles area Saturday, following eight days of immigration enforcement demonstrations.
