House Homeland Security Committee Chairman Michael McCaul (R-Tex.) said Sunday that he thinks Edward Snowden was "cultivated by a foreign power" to leak sensitive information about the U.S. intelligence community's surveillance efforts.

"I don't think Mr. Snowden woke up one day and had the wherewithal to do this all by himself," McCaul said on ABC's "This Week." "I think he was helped by others."

The congressman stopped short of saying Russia, which has granted asylum to Snowden, was connected to the former National Security Agency contractor's actions. "I can't give a definitive statement on that," he said.

McCaul was responding to comments from House Intelligence Committee Chairman Mike Rogers (R-Mich.), who said Sunday: "I believe there's a reason [Snowden] ended up in the hands, the loving arms, of an FSB agent in Moscow. I don't think that's a coincidence."
