The ad urges Congress to plug loopholes allowing terrorists and criminals to buy firearms inside the U.S.

The spot, produced by Mayors Against Illegal Guns, features a clip from an Al-Qaeda propaganda video and an American-born terrorist Azzam al-Amriki, aka Adam Gadahn.

The narration says, “The latest Al-Qaeda plot instructs terrorists on how to buy guns in America.”

Al-Amriki says, “This is a golden opportunity. America is absolutely awash with easily obtainable firearms. You can go down to a gun show and come away with a fully automatic assault rifle, without a background check.”

The terrorist then asks his fellow travelers, “So, what are you waiting for?”
