VIDEO: McCain pushes heavier U.S. involvement in Libya

Benghazi, Libya (CNN) -- Libyan opposition leaders received a major morale boost Friday when a top U.S. senator made a surprise visit to the rebel stronghold of Benghazi and urged greater American involvement in the bloody campaign to oust strongman Moammar Gadhafi.

The visit from Sen. John McCain, R-Arizona, came a day after the United States said it was deploying predator drones to Libya.

McCain said the drones would increase NATO's capability in the war-torn North African country, but not enough to make up a shortfall in assets needed to break a "significant degree of stalemate."

He said he was against U.S. troops on the ground -- echoing Obama administration policy -- but argued that Western powers need to do more to "facilitate" the delivery of weapons and training for the rebels.
