Ah, now I understand a comment that someone made a few days ago. I don't have the original comment, but I know it confused me at the time.
I think the comment said/meant something like this: The telephone call transcript that Schiff was reading to Congress was a fake transcript, leaked to him by a TRUMP insider.
I'll go even further. Perhaps it was a full-blown canary trap. Recall that the original transcript was placed in a top-secret vault, so that accessing it inappropriately and leaking it would be a crime. What if Trump's team substituted a false transcript for the real thing. Schiff then accessed and read out the false transcript, (1) making him look like an idiot, and (2) incriminating him in a federal crime.
Then Trump released the true transcript, sealing the deal.
