Terror plot against the Pentagon averted yesterday

Rezwan Ferdaus, a 26-year-old man from Massachusetts, was arrested Wednesday for allegedly plotting an attack on the Pentagon and the U.S. Capitol with a remote-controlled model aircraft filled with C-4 plastic explosives.

Ferdaus, who has a physics degree from Northeastern University in Boston, was also charged with trying to provide material support and resources to al-Qaeda to help the terrorist organization carry out attacks on U.S. soldiers overseas.

Today on American Morning, CNN national security contributor Fran Townsend explains how serious of a threat Ferdaus was and how the investigation played out.
