Surprise U.S. Immigration and Customs Enforcement sweeps in downtown Los Angeles on Friday prompted fierce pushback from elected officials and protesters.

"As Mayor of a proud city of immigrants, who contribute to our city in so many ways, I am deeply angered by what has taken place," Bass said. "These tactics sow terror in our communities and disrupt basic principles of safety in our city. My office is in close coordination with immigrant rights community organizations. We will not stand for this."
