On Meet the Press on Sunday morning, Mitt Romney supporter (and former GOP rival in the Republican presidential primaries) Newt Gingrich admitted that Romney wasn’t telling the truth about his tax plan.

Ouch. Are even Republicans backing off the Romney tax spiel?

...

GINGRICH: I think you got to look carefully at how Romney structured, what he said is, something that frankly true supply siders don't necessarily love but it's good politics, he said, “I will close enough deductions that wealthy Americans will not get a net tax cut." Now, that's a pretty clear description.

Senior Obama Campaign Adviser Robert GIBBS: Let me just say this. Standing on the stage with you in Arizona, this is what Mitt Romney said.” Number one, I said today we're going to cut taxes on everyone across the country, by 20%, including the top 1%.” Mr. Speaker, you mentioned that your opponent, Mitt Romney, had a problem with being dishonest in the primary. My question is, was he dishonest when he said that?

GINGRICH: I think it's clear he changed.

GIBBS: So we don't disagree that he changed.
