"It's highly probable if you set up a server on the outside and you are a high-ranking government official, especially the secretary of State, that many countries got into that server," Nunes said in an interview on Hill.TV's "Rising" that aired Thursday.

"So, do I have specifics? No, but if I had to bet money, I would have said this back when we were looking for the 33,000 emails," he added.

Clinton's private email server has long been a target for Republicans.
