They haven't. They just keep saying "WE HAVE EVIDENCE" and then never show it. So this whole 'we get mad at everyone demanding evidence from the people constantly promising evidence' thing is starting to wear a little thin. Rudy in October was telling me that Hunter Biden's laptop contents were horrific beyond words, all that got released was a bunch of dick pics. Now he's telling me that they have indisputable evidence of treason at the highest levels of government and hasn't shown a damn thing.
Frankly, the time to put up or shut up was 2 weeks ago.
