Fox News – Newt Gingrich is preparing to quit his Republican presidential run, but not without leaving behind a multi-million dollar debt to consultants and other companies across the country.

With the candidate set to make his exit official Wednesday afternoon, a close look at his finance records reveals a free-spending machine that ran up a million-dollar debt in private jet flights alone, along with other services and benefits that left the unpaid bill at a whopping $4.3 million at the end of March, according to the latest filing with the Federal Election Commission (FEC). The campaign says it has paid off $500,000 of that total, which still leaves a $3.8 million tab.
