How was that a lie? The statement from Mueller's team was vague and hardly a real rebuttal. It just says that it's not accurate and provides no clarification at all.

They had two independent government sources, which doesn't even come close to comparing to this story where the entire source is a single repairman who can't even get their story straight.

And there's a very big difference between being fed wrong information from two sources and not doing enough to verify it, in a time where said information could be crucial, vs "lying" as you imply, which is what NY Post is doing.
