The acting director of U.S. Immigration and Customs Enforcement has issued a statement warning of neighborhood and work site sweeps across California.

The statement was issued one day after Governor Jerry Brown declared California a "sanctuary state."

"What the acting director basically told us is things they're already doing," Sacramento immigration attorney Thomas J. Baker said in response to the announcement.
