He also has no grounds to do so, nor is there a point. The speediest way would be to invoke Section 4, get a simple majority of cabinet secretaries to approve and declare Pence as acting president until Congress considers the issue and the inevitable objection. The 2/3rds in both houses restriction doesn't apply, especially not in this scenario given how close we are to the end of the term - there's simply not enough time for the entirety of the process to play out. That doesn't remove Trump from office - he keeps the title, Pence would only temporarily take over the duties. Since Trump's term ends in 2 weeks regardless, it would be a giant waste of everyone's time. There will be a lot of pearl clutching for the next couple of days, and a lot of posturing, but ultimately it's hard for me to imagine Trump getting charged with anything - he did call for people to protest the vote count, he never told anyone to storm the building, that was done by a small number of crazies that were fairly quickly dealt with and dispersed. I don't think either Pence or Congress will waste time on a meaningless gesture. Keep in mind, Section 4 was designed for cases where the president is unable to fulfil his duties, for instance due to Ill health, and has never been invoked, so that in and out of itself would be unprecedented.
