(CNN) - One of Ron Paul's chief supporters – his son, Kentucky Sen. Rand Paul - said Friday that Newt Gingrich stood opposed to tea party values.
"I got elected with a lot of the tea party support and the tea party movement," Sen. Paul said on CNN "Newsroom."
"The tea party was a lot about people unhappy with Republicans voting for bank bailouts. We thought they sold out our limited government views when they voted to send taxpayer money to big banks. Unfortunately, Newt Gingrich was right there with them being paid by Fannie Mae and Freddie Mac. It goes against everything that the tea party stands for."
The assault on Gingrich comes as Ron Paul, a three-time presidential candidate and Texas congressman, aired a blistering television ad in Iowa and New Hampshire that slams Gingrich for "serial hypocrisy," saying the former House speaker had cashed in after leaving Congress by becoming a lobbyist.
Gingrich has denied charges he was paid for his connections in the House of Representatives, pointing to the fact that he never registered as a lobbyist in Washington.
On Friday, Rand Paul said voters looking for true conservatism would do best by looking past Gingrich and to his father.
"I don't think anybody's been more conservative with the taxpayer dollar than Ron Paul in the last 20 years in Congress," Sen. Paul said on CNN.
He pointed to the Ron Paul campaign's organization in Iowa as evidence of his father's chances of success.
"We have a lot of county Republican chairmen endorsing him this time around," Sen. Paul said. "We have state representatives who have endorsed him, so we have a ground game and it's the one advantage we have over Gingrich. Not only does my father have a conservative voting record, he was against the bank bailouts, against the individual mandate behind Obamacare and he has a ground game. Gingrich has no ground game."
