Partly violent demonstrations broke out in Los Angeles in June in protest against the fact that new raids had taken place in the federal government's escalated crackdown on migrants lacking residence permits.
Donald Trump then went over the head of California's governor, Democrat Gavin Newsom, and gave orders for the state's national guard to intervene together with marine soldiers. The soldiers had the task of protecting federal buildings and protecting migration agents during interventions.
4,000 men from the national guard and 700 from the marine corps were sent out onto the streets of the metropolis. It is still not clear whether the remaining troops will remain deployed.
The deployment began at the beginning of June and was planned to last for 60 days.
A district judge initially stated that Trump broke the law when he called in the national guard against the governor's will, but a higher authority later found that it is likely that the president had the authority to give the order. The court case is still not settled.
