On the heels of major shows of force by federal immigration agents in Southern California, a judge is set to rule in a lawsuit seeking to halt immigration raids in Los Angeles. The developments again thrust a spotlight on a region that emerged weeks ago as an epicenter of large-scale immigration raids by the Trump administration – and of tense protests against the actions that often yielded arrests of their own.

Federal immigration authorities say they've arrested about 200 immigrants suspected of being in the country illegally during raids on two California farm sites.

ACLU attorneys urged a federal judge in a downtown Los Angeles courtroom to temporarily block what they describe as a wave of unconstitutional immigration raids sweeping across Southern California.
