Grover Norquist: George H.W. Bush 'Lied' To America (VIDEO)

Grover Norquist took a shot at George H.W. Bush on Sunday over comments the former president made about his anti-tax pledge.

“When George Herbert Walker Bush ran for president, he promised the American people he wouldn’t raise their taxes,” Norquist said on ABC's 'This Week'. “He lied to them. He broke his commitment to them and they threw him out of office four years later.”

Last month, Bush criticized Norquist's anti-tax pledge as too strict.

“The circumstances change and you can’t be wedded to some formula by Grover Norquist. It’s – who the hell is Grover Norquist, anyway?", he had said.

Bush famously accepted the 1988 GOP presidential nomination by saying "read my lips: no new taxes" before going on to raise taxes as president.

Norquist also fired back at comments Jeb Bush made against the pledge.

“Something that both Jeb Bush should have been a little bit aware of, and his father, that commitment that most Republicans who run for office make is to the American people and to the people of their state," Norquist said.

The Bush family aren't the only Republicans to criticize the pledge. In June, South Carolina Senator Lindsay Graham said that he supported eliminating tax cuts for the rich.

"When you talk about eliminating deductions and tax credits for the few, at the expense of the many, I think over time the Republican party's position is going to shift. It needs to, quite frankly, because we are $16 trillion in debt," he said.

Oklahoma Senator Tom Coburn wrote an op-ed in the New York Times last month calling the Norquist "increasingly isolated politically" and the pledge a "tortured definition of tax purity."
