Actually read more than the headlines on the link I posted, ong.

The Jan 6 stuff against Trump isn't about the protest. It's about his personal efforts to stall the electoral process and the peaceful transfer of power.

I get that less of this hits the news in other countries, but there's so much evidence on his factual knowledge that he lost and that he was politically strong-arming even his own vice president to break the law. E.g. the now famous, "You're too honest." audio tape where Trump is trying to convince Pence to break the law and Pence wont do it.
