What truth? Okay, for starters:
1) Who told people where congressmembers' private offices were?
2) Why were banned tours given to rioters the previous day? Who gave them?
3) How much talk was there before the fact implying some people knew it would happen?
4) What was Trump doing and saying for the several hours of the riot before he spoke to the nation?
5) Why did Trump tell the crowd hewould march with them (he actually also said "we"), and instead went to a TV to watch them?
6) who removed the panic buttons, and why?
7) why was help denied to the congress, when they pleaded for it?
Oh there's more...
Hmm, those sound like questions...not truths. Questions that should probably be answered. Too bad this committee won't go about the business of finding any truth around them. They already have the answers to those questions in their minds, before they've even had a meeting.
But...I do have the answer to one of the questions for you, already.
#5: that video of trump in the tent watching those tvs was not then watching the riot. That is just partisan left wing media telling that lie.
All you have to do is think about it, and actually watch the video, closely! Look at the video, what was on the monitors in that tent? It was just cameras pointing at a stage, a stage that trump was about to go make a speech on. That video was taken before the trump speech, not after.
Also, there is no way that anyone close to the trump campaign would ever let don Jr make a cell phone video of them watching the riot on TV, especially with all the high profile people present, who would have a LOT to lose if a video like that, of then watching the riots on TV, were to ever get out, and dancing and celebrating it.
That question is a partisan question designed with only one thing in mind, to slander and damage the trump campaign, and they plastered that all over cnn and other left wing shows, and nobody ever even actually looked at the video, they just all took their word for it.
I imagine you will find a lot of that during these hearings.
