U2's Bono says he is not involved in efforts by U.S. legislators to use his band's concerts to raise campaign money.

Sens. Hillary Rodham Clinton (D-N.Y.) and Rick Santorum (R-Pa.) and other politicians have scheduled fundraising events in private suites during shows for U2's North American Vertigo tour, which runs through December.

In a message posted on the band's Web site, the executive director of DATA (Debt AIDS Trade Africa), an Africa advocacy group that Bono helped found, said: "Neither DATA nor Bono are involved in these [fundraisers], and they cannot be controlled. The U2 concerts are categorically not fundraisers for any politician; they are rock concerts for U2 fans."

Clinton expects 18 supporters willing to pay $2,500 each to benefit Democrats to join her at a U2 concert at MCI Center next week. Messages left with her office were not immediately returned.

Santorum's press secretary, Robert Traynham, said yesterday that the senator's decision to hold a fundraiser during Sunday's Philadelphia show is based on his "deep respect and admiration for Bono and their work together over the last few years to fight the global spread of HIV-AIDS."
