Gadhafi's Libya On the Brink of Collapse

On this week's Washington Report, David Sanger, chief Washington correspondent for the New York Times, joins Kerry Nolan to discuss Moammar Gadhafi's 42-year rule, which seems to be on the brink of collapse as Libyan rebel forces spread throughout Tripoli. The Libyan leader remains defiant and his exact wherabouts are unknown as the international community continues to call for him to step down peacefully. Sanger weighs in on why the rebels have suddenly been able to advance and what the impending endgame means for the Obama administration and nations like North Korea and Iran.
