Coup attempt. That's nonsense. You should for all our education, post Trump's speech. We could read it together and find those parts that incited those who stormed Capitol Building. I read it a while ago and couldn't find the bit where he incited violence. Most of it was about voter fraud. When he's impeached all he has to do is prove, with what evidence he has, that what he was saying was fact. It will be a good platform for him to be able to present any evidence he has to a wider audience.
He riled up the crowd, Rudy and his sons also helped the frenzy.
Then there was the whole 2 previous months where he was exploring every option to overturn the result and convincing his followers it was rigged, without any evidence.
