Former House Speaker Newt Gingrich is slamming Sen. John McCain for criticizing Sens. Ted Cruz and Rand Paul, saying it’s “sad” for someone who was once known as a maverick in Congress.

“What I find sad about Sen. McCain’s recent comments both to Ted Cruz, when Ted Cruz was frankly raising legitimate questions [about Benghazi] and 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 Thursday on Fox News.

He continued: “Of everybody I know in the Senate, I didn’t know anybody who had a better record of bucking the leadership, doing what he thought mattered, marching to his own drummer.
