"Who the hell is Grover Norquist anyway?"

President George H.W. Bush, the one-term chief executive and father of the more recent President George W. Bush, lashed out at taxpayer advocate Grover Norquist in an interview with Parade Magazine, saying Mr. Norquist’s no-new-taxes pledge is a mistake.

Mr. Bush, who famously broke his “read my lips” pledge by raising taxes, said lawmakers can’t be bound by those kinds of promises because circumstances change.

“The rigidity of those pledges is something I don’t like. The circumstances change and you can’t be wedded to some formula by Grover Norquist. It’s—who the hell is Grover Norquist, anyway?” Mr. Bush told the magazine in an interview published this weekend.
