After Congressman Timothy Johnson (R-IL) called Grover Norquist's Taxpayer Protection Pledge “disingenuous and irresponsible,” and claimed he "never signed anything," when told he was, in fact, a signor, someone from ATR got on the case:
Americans for Tax Reform provided Roll Call with a copy of Johnson’s signature on the tax pledge from 2002. On Feb. 26, 2002, Johnson pledged to “ONE, oppose any and all efforts to increase the marginal income tax rates for individuals and/or businesses; and TWO, oppose any net reduction or elimination of deductions and credits, unless matched dollar for dollar by further reducing tax rates.” Matt Bisbee, Johnson’s press secretary at the time, signed as a witness.
Realizing the jig was up, Johnson admitted to signing it but said that it was "no longer binding for him," because really, the TPP is NBD:
“I would never in a million years have considered this as some kind of a locked-in-granite pledge. Frankly, I didn’t even remember it. That shows you how obscure it was to me,” Johnson said.
