He was more so using an expression but in an interview with Parade former President George H.W. Bush asked "who the hell is Grover Norquist?"
PARADE: During your presidency you gave in on your “no new taxes” pledge. You’ve been vindicated in many respects for that decision. I wonder how you view the “no new tax” pledge from Grover Norquist that seems to be requisite for GOP political candidates.
GB: 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?
Norquist, of course, is the president of Americans for Tax Reform.
