Arizona’s John McCain, chairman of the Senate Armed Services Committee, joined Democrats over the weekend in calling for a special select committee to investigate Russian cyberattacks and their effect on the election.

His position puts him at odds not only with the incoming GOP president but with Senate Majority Leader Mitch McConnell, who favors allowing the Intelligence Committee to take the lead on the inquiry.

“We need a select committee. We need to get to the bottom of this," McCain said. "We need to find out exactly what was done and what the implications of the attacks were, especially if the had an effect on our election.

McCain also said during a CNN interview that “reality is going to intercede at one point or another."

President-elect Donald Trump calls reports of Russian hacking "ridiculous" and his transition team dismissed the CIA assessment, saying it was the work of the same people who claimed Iraq had weapons of mass destruction.
