Politicians are in heated debate about the $14.3 trillion national debt ceiling. But their personal debt can also be eye-popping.

Politico reports that Republican presidential candidate Newt Gingrich owed at least $250,000 and as much as $500,000 to luxury jewelry company Tiffany & Co.

We checked the store website but couldn’t find any one item for that amount, although a few baubles here, a few watches there, and it all adds up.

So what did he buy? We don’t know, and his spokesman won’t say.

The former House speaker in 2005 and 2006 carried $250,001 to $500,000 in debt to Tiffany’s, according to financial disclosures filed by his third wife Callista, who was employed by the House Agriculture Committee until 2007, Politico reports. Financial disclosure forms ask for ranges rather than specific amounts in many categories.

She reported the liability was on a Tiffany charge card and indicated it was her spouse’s debt. It was not clear whether he has paid off the debt.
