I need a word..

I have a slight dilemma...

I need a word to describe that thing people do,whereby they say something out loud and in public,and then proceed to deny it as though their revised version of the facts must be true,by virtue of having said it.

No,no,..it's not 'lying',because that implies that the person knows that there is a marked disparity between what they said then,and what they are saying now.

I'm talking about those instances in which the offender clearly believes the newly crafted account of events,and fully expects that we'll believe it too!

Matthews: 'Do you believe Barack Obama may have anti-American views?"..

Bachmann: 'ABSOLUTELY!..I'm very concerned that he may have anti-American views'.

Straight forward question...Enthusiastic answer..

I've been speaking English for some time now,and feel like I have at least a journeyman's grasp of it's usage.

Try as I might,I can't find an iota of ambiguity in that exchange.

And yet,..

'I'm not saying that his views are anti-American,that was a misreading of what I said'...

She went on to complain in a separate interview,that she had been the victim of Chris Matthews' 'trap'..

What the fuck!??..

I'm convinced,that she's convinced,that we're convinced that her 'clarification' makes perfect sense,and that her simple act of rebuttal has successfully warped the fabric of time and space,bringing us to an alternate universe in which she maintains her credibility.

If there's not a word to describe that phenomenon,there really does need to be one.
