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.

Federal agents conducted immigration enforcement raids on Thursday on state-licensed marijuana nurseries in an agricultural region of coastal Southern California, where they were confronted by throngs of angry protesters.

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.
