Newt Gingrich: John McCain 'Disappointed,' 'Saddened' Me (VIDEO)

Former House Speaker Newt Gingrich said he was "saddened" by Sen. John McCain (R-Ariz.), who railed against Sen. Rand Paul (R-Ky.) for his nearly 13-hour filibuster this week.

"I'm really disappointed in John McCain, and I'm very saddened by it," Gingrich said during an interview on CNN's "The Situation Room" Friday. "McCain in his younger years was a great maverick. He took on his party all the time."

McCain slammed Paul on Thursday, saying the Kentucky senator's rant against extrajudicial drone killings was "simply false." HuffPost's Mike McAuliff reported earlier:

Paul took to the floor Wednesday for nearly 13 hours, hoping to pressure the White House to declare whether or not it might use a drone to strike an American citizen in the United States.

McCain, a former Vietnam prisoner of war, was not impressed.

"I watched some of that, quote, debate, unquote, yesterday," McCain said. "I saw colleagues who know better come to the floor and voice some of this same concern, which is totally unfounded.

"I must say that the use of Jane Fonda's name does evoke certain memories with me, and I must say that she is not my favorite American. But I also believe that, as odious as it was, Ms. Fonda acted within her constitutional rights, and to somehow say that someone who disagrees with American policy -- and even may demonstrate against it -- is somehow a member of an organization which makes that individual an enemy combatant is simply false," McCain said, hitting his lectern for emphasis. "It is simply false."

McCain said it was "ridiculous" and "a stretch of the imagination" to "allege or infer that the President of the United States is going to kill somebody like Jane Fonda, or somebody who disagrees with the policies."

This isn't the first round of criticism Gingrich has hurled at McCain. On Thursday Gingrich told Fox News McCain's comments were "sad."
