The Trump administration announced Tuesday it will withdraw 2,000 National Guard troops from Los Angeles, reducing by half the force deployed last month to curb unrest following protests over immigration raids.

Los Angeles Mayor Karen Bass has declared a local emergency and imposed a 10-hour curfew for downtown Los Angeles in response to escalating protests over U.S. President Donald Trump’s immigration raids.

Authorities in Los Angeles have arrested at least 56 people during ongoing protests against immigration raids, according to the LAPD.
