Gen. Martin Dempsey, joint chiefs of staff chairman, said in an interview aired Sunday that it would not surprise him if the Russians or Chinese have obtained access to the classified information that NSA leaker Edward Snowden swiped while a government contractor.
"No, it wouldn't surprise me," Dempsey said in an interview on ABC's "This Week" with Martha Raddatz.
"[Snowden] has caused us some considerable damage to our intelligence architecture," Dempsey said. "Our adversaries are changing the way that they communicate. My job is to protect the country. So I am very concerned about this."
