Liu Blasts Inquiry into His Fundraising at Mayoral Forum

Put up or shut up.

That was the challenge issues to federal prosecutors by city Comptroller John Liu at a mayoral forum Thursday night.

Liu's fundraising has been probed as part of a multi-year investigation that has resulted in the arrest of two campaign aides. Liu rattled off a list of grievances from phone taps to interrogations. He told the audience in East Harlem in his closing statement, "It's time to put up or shut up already because I've got an election to win. "

The remarks drew applause and seemed to stun rival mayoral hopefuls. Republican candidate Tom Allon told The New York Times he was "shocked" by Liu's comments.

Liu has not been accused of wrong doing, but he said a cloud remains over his head.

His campaign associates, a former campaign treasurer and a fundraiser head to trial on April 15. They are accused of using straw donors to get around campaign finance laws.
