In the days before protests erupted in Los Angeles, the Trump administration stepped up its efforts to detain migrants — taking into custody those who arrived for routine check-ins while also conducting workplace raids that have sent waves of fear across Southern California and beyond.

A federal judge will hold a hearing on Thursday over California’s request to block the Trump Administration from using troops in Los Angeles to quell unrest sparked by Immigration and Customs Enforcement (ICE) raids as part of the President’s mass deportation effort.

Police in Los Angeles, where protests over federal immigration enforcement raids erupted a week earlier and sparked demonstrations across the country, used tear gas and crowd-control munitions to clear out protesters on Saturday.
