Director of ICE says raids will increase across California

The White House is looking to increase the crackdown on undocumented immigrants after California's decision to become a sanctuary state.

The head of Immigration and Customs Enforcement says his organization will have no choice but to conduct workplace and neighborhood immigration raids across the state.

Acting ICE Director Thomas Homan says California becoming a sanctuary state "undermines public safety and hinders ICE from performing its federally mandated mission".

Under the state's new law, state and local police will have major restrictions on how and when they can communicate with immigration officials.

Governor Brown signed a law making California a sanctuary state on Thursday.
