Gingrich: McCain's attack on Paul 'sad'

Gingrich also praised Sen. Ted Cruz's (R-Texas) sharp questioning of now-Secretary of Defense Chuck Hagel during his confirmation hearing, which also drew McCain's ire. 

"What I find sad about Sen. McCain’s recent comments both to Ted Cruz, when Ted Cruz was frankly raising legitimate questions and again yesterday with Rand Paul, is, you know, when I first knew John McCain in the House — he was a maverick. In the Senate, for years, he was a maverick," Gingrich said.

"Of everybody I know in the Senate, I don’t know anybody who had a better record of bucking the leadership, doing what he thought mattered, marching to his own drummer. And I think that it’s unfortunate but I think frankly it doesn’t hurt Ted Cruz and it doesn’t hurt Rand Paul — it hurts John McCain. The country is moving on, we’re in a new era, people know that these are legitimate questions."

On Wednesday, Paul held up Brennan's nomination in order to get the Obama administration to say whether it could launch a drone strike against a citizen not engaged in combat on U.S. soil. The filibuster prompted Attorney General Eric Holder to send Paul a short letter saying the president does not have authority to kill non-combatants in America.
