What can the US Congress legally do to prevent Trump from running for US President again?

This seditious tyrant must be legally stopped from wreaking havoc and damaging American Democracy again.

Trump is on TV right now justifying the attack he instigated yesterday on Capitol Hill and at the same time acknowledging for the first time that Biden won. Is he merely trying to save any opportunity to make a comeback in 4 years?

What do you think should be a fair and just response to Trump’s attack on Capitol Hill?
