In January, Rogers said on NBC’s “Meet the Press” that he was investigating whether Snowden had help from Russia in stealing highly classified documents from the National Security Agency.
Although Snowden called Rogers’s claim “absurd,” Rogers reiterated his suspicions on the show again on Sunday.
All counterintelligence officials believe Snowden has been under the influence of Russian intelligence services, Rogers said.
“We believe he is. I certainly believe he is today,” he said. “For the investigators, they need to figure out when did that influence start?”
Snowden has been living in Russia since last August, after its government granted him temporary asylum.
Rogers said Snowden's support of “this very activity of brazen brutality in expansionism of Russia" indicates he is under Moscow's influence.
Rogers added, “I do believe there’s more to this story.”
