Thanks for the pointer. Here's the comment you refer to:

As danso notes, the NY Times editor and Amazon's Carney have now made pretty unequivocal contradictory statements, with little room for them both to be right without one of them outright lying. (And I don't think either one would go on the record here with an outright lie.) Except that the NY Times says "But he [Olson] said he was never confronted with allegations of personally fraudulent conduct or falsifying records, nor did he admit to that... If we had known his status was contested, we would have said so". That is, they can both be telling the truth if Olson was lying to the Times about his departure.
That's my prediction for how this shakes out. And in that case, the Times will have egg on their face for having not properly vetted their sources.
