Newt Gingrich’s campaign remains roughly $600,000 in debt, two months after it reported deep debts and a long list of creditors, newly released campaign spending records show.

Fundraising by the former House speaker’s campaign has stepped up markedly since then, and Gingrich just last month cut by half the $1.2 million owed in October 2010. Still, several outstanding creditors remain.

At the end of last year, he owed a total of $1.19 million, nearly a half-million dollars of that to InfoCision, an Ohio telemarketing firm that specializes in fundraising for conservative political, Christian and non-profit groups.

Gingrich’s campaign has made a big dent in that debt: InfoCision officials said late last month that the campaign paid off its $471,000 bill in full.

Gingrich also reported paying a sizable amount to himself and his companies, which his spokesman said amounted to reimbursements for campaign expenses.

The campaign paid $67,000 to Gingrich Productions, led by his wife, Callista Gingrich, for “Web hosting” and “email hosting.”
