Report: Gingrich had $1M in credit at Tiffanys

Last month, campaign finance disclosure forms revealed GOP presidential hopeful Newt Gingrich and his wife ran up a debt at famed jeweler Tiffany and Co. somewhere in the range of $250,000 to $500,000.

The bill could have been a lot larger, however, as the former House speaker's personal financial disclosure filing will "show that the Gingriches had a $500,000 to $1 million line of credit at Tiffany's, that it has a zero balance, and it has been closed," The Washington Post reports.

The revelation was confirmed for the Post by Joe DeSantis, a spokesman for Gingrich, who added that all debts to Tiffany had been paid in full. DeSantis offered the newspaper no further details.

Gingirch has denied any special treatment at Tiffanys, telling Bob Schieffer on CBS' "Face the Nation" broadcast in early May: "We're private citizens. I work very hard. We have a reasonably good income. I currently owe nothing, except I owe one mortgage on a house that's rental property in Wisconsin. Everything else is totally paid for. My home is paid for. My cars are paid for. We don't have a second house. We don't do elaborate things."

Gingrich's presidential campaign seems to be coming off the rails, despite his protestations to the contrary, and this latest report probably won't help things.

On Tuesday, two top fundraising aides for Gingrich resigned. Other key members of Gingrich's team, including his campaign manager, resigned on June 9, questioning his commitment to the 2012 presidential race after the candidate went on a Greek cruise with his wife.

Since launching his campaign in May, Gingrich has also angered his party by criticizing a congressional Republican plan to scale back the Medicare health insurance program for the elderly and disabled.
