John McCain: Trey Gowdy is an 'honest man'

Sen. John McCain, R-Ariz., is defending the House Select Committee on Benghazi amid accusations it is simply a political ploy to hurt Hillary Clinton.

"Well, I think that every major investigation that you and I have seen leads some different directions. Certainly Watergate was a great example of that," McCain, who is chairman of the Senate Armed Services Committee, said in an interview on PBS's "Charlie Rose" Monday night.

McCain added that while "there's been attempts to" discredit the House committee, he will continue to withhold judging it until it finalizes its conclusions surrounding the Benghazi attack.

He was however quick to defend the chairman of the committee, Rep. Trey Gowdy, R-S.C.
