Sen. John Mccain, R-Ariz., is in Libya on Friday meeting with rebels fighting to overthrow Moammar Gadhafi.
         
There were shouts of joy from Libyan people as  McCain arrived in Benghazi's "Freedom Square" to tour a makeshift "martyr's wall."

McCain, the top Republican on the Senate Armed Services Committee, is one of the strongest proponents of U.S. military intervention in Libya.

The Arizona senator was surrounded by Libyan people, who were quick to share their anger and frustration with Gadhafi  -- and their gratitude to America.

"The American people support you very strongly and we know it is necessary to help as much as we can," McCain said.
    
Meanwhile, President Barack Obama has authorized the use of armed predator drones against forces loyal to the Libyan dictator.  It is the first time that drones will be used for air strikes since the United States gave NATO control of the operation.

U.S. Defense Secretary Robert Gates says despite the new use of predator drones in Libya, the U.S. will continue to maintain a limited role.  And he insists U.S. forces will not touch Libyan ground.
