(CNN) - Former House speaker and presidential candidate Newt Gingrich had another line of credit at the high-end Tiffany & Co. jewelry store, a Gingrich spokesman confirmed Tuesday.

Gingrich's personal financial disclosure campaign filing will show he had a line of credit of up to $1 million with the store, in addition to a revolving charge account revealed last month.

Gingrich spokesman Joe DeSantis confirmed that when the form is made public it will show that Gingrich and his wife Callista “had a $500,000 to $1 million line of credit at Tiffany's, that it has a zero balance, and it has been closed."
