Attached are all the transcripts. Read them.
Note that all the interviews took place during 2017-18, when Nunes controlled (obstructed) the House Intelligence Committee. Schiff was the minority ranking member in 2017-18. The GOP majority ran the show back then. The transcripts make that very clear.
Note that Obama Administration officials showed up and testified truthfully before the committee. Contrast Donald Trump and many of his circle who refused subpoenas in both Russian and Ukraine probes. Why? Because they did not want to be stuck either admitting to criminal wrongdoing or lying under oath.
The Mueller Report (very few of you bots have even read it) made clear that lack of access to key witnesses (Trump circle lawyering up) was a major obstacle in gathering vital witness information that prevented Mueller from gathering ample evidence to charge Conspiracy.
And Nunes (not only a piece of shit, but a really stupid piece of shit) was in bed with Trump, covering up the criminal wrongdoing in violation of Nunes’ oath of office. Nunes had the power to release all these transcripts in real time.
The witnesses you cite were not part of the Trump campaign. Nunes called them. They testified truthfully. And feel free to spend today reading them.
