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.

Thousands of “No Kings” protests are taking place on Saturday across the United States, with dozens of demonstrations planned in Southern California. The “No Kings” movement started in opposition of policies being instituted by President Donald Trump and his administration.

Demonstrators gathered in communities large and small. Many events on the East Coast have ended, but police clashed with some protesters in L.A.
