That was a pretty horrendous editorial decision. They could at least have decided to point out that he was wrong if they were worried about ascribing intent to him. But even that fails in situations like this where the lie is just part of a larger con to deflect from the truth. But I suppose decisions like that are why Trump can get away with these utterly obvious, child-like diversions.
Those guys are paragons of honesty by comparison. At least they give a solid date for an event that can be falsified (even if they are then forced to revise the issue at that point), and the date is the revelation. Trump is trying to have it both ways - pretending to be transparent and responsive in providing a date for the revealing of information, but then he just ignores the issue after that point, hoping that the previous appearance of transparency was sufficient to quiet the chatter long enough for the issue to pass in the media.
