Back taxes to be paid on Sen. McCaskill plane

Senate Contracting Oversight subcommittee Chair Sen. McCaskill asks questions on Capitol Hill in Washington, Thursday, July 29, 2010, during the subcommittee's hearing to examine contract mismanagement at Arlington National Cemetery.

U.S. Sen. Claire McCaskill says her husband's company is selling a plane she used for Senate business, and more than $280,000 in unpaid property taxes on it are being paid.

The Missouri Democrat says checks covering the taxes were to be sent Monday to St. Louis County, where the eight-seater is housed.

McCaskill's Senate office paid to use the plane, though she repaid the U.S. Treasury for the flights. McCaskill says she convinced her husband to sell the plane owned by his company and that she does not plan to ever set foot on it again.

McCaskill says the unpaid taxes are a mistake. She says there was no attempt to hide the plane's existence and that monthly sales taxes have been paid on the plane for several years.
