A bill to grant security for the families of U.S. Supreme Court justices unanimously passed the Senate Monday.

The Supreme Court Police Parity Act would provide police protection to the immediate families of the nine justices and other officers of the court, if the "Marshal determines such protection is necessary," the legislation says.
