Massachusetts lawmaker Barney Frank flew to the Virgin Islands for free on a private jet loaned by a Maine congresswoman’s billionaire fiancé, prompting political rivals to remind voters it’s time for a change.

Frank flew last year on the jet loaned to him Paloma Partners boss S. Donald Sussman, the fiancé of U.S. Rep. Chellie Pingree, D-Maine, whose company received a $200 million federal bailout as part of the rescue package for insurance giant AIG, according to the Boston Herald.

Frank, head of the House Financial Services Committee, says the trip was personal and that House ethics officials had no problem with him flying on the plane.

Republicans question the move.

“Barney Frank’s acceptance of a lavish gift from a hedge fund manager, an industry he is responsible for regulating, is a troubling conflict of interest that raises serious questions about his judgment,” says Republican National Committee spokesman Parish Braden.

“Typical. Barney keeps showing how career politicians work — they use our dollars for their favors. It may be legal, but it’s wrong and that’s why we need a change.”

Frank is facing competition from Republican Sean Bielat, who is hoping to tap voter dissatisfaction to unseat the Democratic fixture in November’s elections.

“It’s not surprising that when a challenger who doesn’t have much of a political background or a name running against a 30-year incumbent, that the race would really be a referendum on that incumbent’s performance,” says Bielat, according to the Patriot Ledger.
