The U.S. Border Patrol chief in charge of overseeing the agency's El Centro, California, sector slammed a state law that limits cooperation with federal immigration authorities after he said a drunken driver in the country illegally killed someone in a crash. 

Gregory Bovino didn't specify the nature of the deadly crash, but tweeted that the suspect was previously convicted of striking his spouse. He added that because of California's "inaction, thanks to SB54, has claimed another life."

Supporters had said SB54 allows law enforcement agencies to target criminals without harming those in the country illegally.

"This bill strikes a balance that will protect public safety while bringing a measure of comfort to those families who are now living in fear every day," then California Gov. Jerry Brown said at the time he signed the legislation.
