The company, Descante Capital Holdings, was uncovered in Salon's reporting on a private jet that Loeffler jointly purchased with her husband, Jerry Sprecher, who is chair of the New York Stock Exchange.
She once used it for an 18-minute hop from a central Georgia town to Savannah.
A Loeffler staffer told The Atlanta Journal-Constitution last February that the senator had paid for the airplane "out of her pocket," but her financial disclosures suggest that isn't true.
Individuals are not permitted to write off the purchase of a jet; only businesses can do that.
The aircraft tracking site Flight Aware says that the jet is "not available for public tracking per request from the owner/operator.".
A Loeffler campaign spokesperson did not respond to multiple detailed questions for this article. »
