Conservative columnist George Will is not a fan of former House Speaker Newt Gingrich (R-GA).

"Newt Gingrich's problems are so far beyond just his multiple marriages and all that," Will told ABC's Christiane Amanpour Sunday.

"His ethanol love affair right now. On the 7th of March he said, 'Let's go get Gaddafi.' On the 23rd of he says, 'I never favored intervention.' He did it on television."

"He's one of these people who says that to understand Barack Obama you need to understand his 'Kenyan anti-colonial mentality.' This is just not a serious candidate," he added.
