Paul: Newt should return Freddie Mac cash

Rep. Ron Paul thinks Newt Gingrich is morally obligated to pay back the consulting fees he raked in from mortgage giant Freddie Mac.

"Well legally he doesn't have to, but I would think morally, him having received this money, yes," Paul said Sunday when asked whether Gingrich ought to apologize and pay back the cash he earned prior to the government takeover of the failing mortgage giant.

"I wouldn't have taken their money, just for the fact that I think it was an immoral thing to take money," the Texas congressman said on NBC's "Meet the Press."

Paul slammed Gingrich during the Republican presidential debate Saturday for accepting from $1.6 million to $1.8 million in consulting fees from Freddie Mac, as reported by Bloomberg News.

Gingrich has defended the consulting work he did while in the private sector.
