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.

Dozens of mayors from across the Los Angeles region banded together to demand that the Trump administration stop the stepped-up immigration raids that have spread fear across their cities and sparked protests across the U.

Marines have moved into Los Angeles to guard a federal building after a week of protests against immigration raids, while communities across the country are preparing for demonstrations against President Donald Trump’s polices this weekend.
