Investigative filmmaker James O'Keefe is at it again, this time in West Texas exposing the U.S.-Mexico border's vulnerability to terrorism.

“No one is on watch, even Osama bin Laden could cross,” O'Keefe says in the latest video released by Project Veritas.

In it, O'Keefe appears dressed as the Al Qaeda terrorist as he walks freely into the U.S.

“If the president or Senator Harry Reid or anyone else tries to tell you that our borders are secure, they are lying to you.” O'Keefe says.  “That was just about the easiest thing I ever did.”

O'Keefe's video starts off by reminding viewers of the constant rhetoric from Obama administration officials.

“The border from a security standpoint is stronger than it's ever been,” said Homeland Security Secretary Janet Napolitano.

“The fence is now basically complete,” President Barack Obama said.

The video then shifts to O'Keefe being taken on a tour by Hudspeth County Sheriff Arvin West who shows where the border wall ends, and a makeshift fence begins.

“If you think four strands of barbed wire is securing the border, then I guess its secured,” West tells O'Keefe.

West doesn't blame border agents for their lack of numbers along the Rio Grande, he blames their bosses in Washington.

“You hear the rumors of boots on the ground and more agents,” says West.  “We've got plenty of agents, they just need to be on the border.”

Already this summer, contractors found a Muslim prayer rug along the Arizona border, and terrorist watch-list suspects were detained crossing into California.
