Trump is literally admitting here that January 6th was about trying to overturn the election.

He's not using the term "January 6th" the way he would need to in order for that to have any real relevance.

On January 6th, there was a concerted effort by the Trump campaign to have members of Congress and/or the VP vote in way that would (in their mind) keep open a path for him to contest the election and be declared the winner. That effort was probably not criminal. You're allowed to lobby Congressfolk. You're allowed to lobby the VP. If a law provides for them to take a vote to reject the electoral results, then it's almost certainly not criminal for them to vote to reject the electoral results. And therefore, it's almost certainly not criminal for people to try to persuade them to vote to reject the electoral results.

He's certainly not admitting that he engaged in a deliberate effort to accomplish that same goal using the violence of a mob.
