Even Henry Waxman is willing to say it:
What does the New York Times say?
My favorite quote, about the prank call to my friend (the sort of person it gives me pleasure to recall) Governor Walker of Wisconsin
Mr. Koch joked that the call could cause him problems. “I was thinking to myself, ‘My God, if I called up a senator or a congressman to discuss something with them, and they heard ‘David Koch is on the line,’ they’d immediately say, ‘That’s that fraud again — tell him to get lost!’ ” he said with a laughYeah, that must suck. You know, I certainly expect my senator to pick up the phone pretty much within five minutes of me calling, myself. I'd hate it if some prankster claiming to be me would so tarnish my reputation as to slow that down to ten or fifteen.
