So you're saying that when Trump is impeached and this goes to the Senate, the whistleblower will have to be revealed. Okay.
Do suspects have the evidence and testimony paraded out for the media for three months before the trial? Do members of the grand jury discuss cases with the press? Having served on one, I can tell you it is quite the opposite. If the impeachment hearings are equated with the criminal proceedings that you mention and everything is all that secret, those involved are behaving inappropriately. Were they ordinary citizens they might even be charged with a crime. By sharing this information with press, the House Democrats are hoping to create some advantage in the coming election. That sounds like they're using their position for political gain. Where have I heard that before?
Trump, Biden, Congress, they're all guilty as hell, IMO.
And if I weren't paying attention, I wouldn't have asked the question. I'm a citizen, not a lawyer. I'm not required to listen to liars without limit.
