There is too much exculpatory evidence to take the time to list here. But if the GOP had conducted hearings re any Democrat, stacked a committee with only people who hated that Democrat with a passion, allowed only testimony that appears damning to that Democrat and allowed no challenge to any testimony and no introduction of any exculpatory evidence, you and other leftists would be screaming FOUL and CORRUPT and UNFAIR and DISHONEST as loud and as long as you could. And you know it. THAT is what calls Liz Cheney and every other member of that Commission's character into question.Which testimony so far do you think should be challenged, and on what grounds?
And what kind of "exculpatory evidence" do you imagine any Republican led "investigation" would present?
That's the thing see, it is turning out that Trump's failed coup was aided and abetted by the majority of Republicans in Congress either overtly or passively.
You can't put the criminals in charge of the courtroom!
If they have something meaningful to say this committee will welcome their testimony.
The committee will NOT allow Republicans to derail the FACTS of the matter with their ridiculous, non-factual, conspiracy-theory, alternate reality horseshit though.
The only requirement is that the hearings stick to only the facts.
Republicans can't do that.
This is why so many of them are defying subpoenas and refusing to testify or pleading the 5th.
