Former Al Qaeda Terrorist: Another Attack Coming in 'Two Weeks'

Thousands of people on the national Terrorist Watch List are still legally allowed to buy guns – and have been doing just that, according to a new report.

The Government Accountability Office says that more than 2,000 suspected terrorists have managed to buy guns in the U.S. from 2004 to 2014.

That makes an overwhelming 91 percent of those on the list who were not blocked from purchasing a firearm.

So, how did that happen?

Gun rights are a "congressional situation," said Stewart Verdery, former Assistant Secretary at the Department of Homeland Security, said on “The Real Story” today.

"There's nothing more micromanaged in the law than how people get their guns, who can be denied."

It’s important to also remember that the watch list is a “huge number of people,” Verdery said. Many are often added by mistake.

But the staggering success rate of these transactions does mean it “perhaps needs to be looked at,” he added.
