Los Angeles County supervisors have voted to extend a program to have sheriff's officials screen inmates' immigration status.

The supervisors approved the proposal Tuesday after months of negotiations between the country's biggest sheriff's department and Immigration and Customs Enforcement.

Dozens of law enforcement agencies across the country renewed similar programs with ICE last year with some changes.

Immigrant advocates have asked the county to end the program, which they say can lead to racial profiling and hurt community policing.

Several dozen people protested against the program outside the meeting.
