Yes there is no record of apologizing on TV, is that what you want (as it was done in private)? Are you trying to say someone else apologies for her from US so it means the thing she said is not true on the transcript (or that generally US government said she apologies in private)?
I'm trying to say when you say a person in question apologizes, you should probably save saying that until you've got a record of it
happening. If you want to say other officials said, second/third hand sources said, etc., then fine, but maybe don't say things you can't actually back up, y'know? Context and framing is ruddy important, and without that one tends to pull entirely too much from the aether.
I do not understand what you are trying to say. State department spokeswoman Jen Psaki acknowledged that the recording was authentic.
Mostly trying to say that you seem to be reading considerably more into what's actually been said than seems warranted. Psaki, who's effectively got a job description that reads "double-speak all day erry day", is going to say something like she did bloody regardless of whether the recording was authentic. Bugger'd sound like that if she were talking about the color of the sky on record.
It's going from "Other official said things" to "Nuland personally apologized for crass words" (when there's any dozen other things regarding the situation she could have been apologizing for) to "Suddenly the US is the prime driving force behind euromaidan." Which is... stretching. Just a bit.
You, possibly -- hell, even probably -- have a record of politicians being politicians. If there's anything
else -- abnormal material support, obvious interpersonal collusion, etc., etc. -- it would be interesting to know, but one internal conversation does not a significant influence or interest make.
