U2 rock giants are unhappy that U.S. politicians from both main parties, including Hillary Clinton, are using their concerts to raise funds.
"The U2 concerts are categorically not fundraisers for any politician. They are rock concerts for U2 fans," a statement from the group's publicist said Wednesday.
Hillary Clinton has "invited" 18 people to join her, on Oct 19, in a luxury suite at Washington's MCI Center to see U2 play during their sold-out Vertigo tour, as long as they contribute $2,500 to the Democratic Party.
Luxury suites at the center cost $7,000 and offer a close-up view of the stage.
"We do a meet-and-greet with the senator, and then go in and listen to music," said Ann Lewis, the former first lady's spokeswoman.
Pennsylvania Republican Senator Rick Santorum is holding a $1,000-a-head fundraiser at U2's show in Philadelphia this weekend.
