The Governor of California, Gavin Newsom, has accused President Donald Trump of a "brazen abuse of power" with the deployment of Marines and US military troops on the streets of Los Angeles.
The Mayor of Los Angeles has imposed an overnight curfew in the city, after violent clashes intensified with demonstrators protesting the Trump administration's programme of mass deportations.
And protests have now spread to other cities including New York, Atlanta and Chicago.
From Washington, Simon Marks reports.
