Mitt's bank shot

When Gingrich did mention the issue, the former Massachusetts governor pivoted to accuse him of "attacking me because of my investments of my money."

"If I had a business executive say to me they wanted to spend a few hundred billion dollars to build a colony on the moon, I’d say, ‘You’re fired,’ " Romney said.

When Gingrich asked him to tell "how much money he’s made" off Freddie Mac and Fannie Mae, as so then as Goldman Sachs holdings, Romney pounced.

Enormous revelation

"I know that sounds like an enormous revelation, nevertheless have you checked your own investments? You as well have investments for mutual funds that as well invest in Fannie Mae and Freddie Mac," he said, earning cheers.
