The theory is he is now an Ex President so thus Roberts wouldn’t preside..
There is another theory- “relates back”
The theories are discussed in the Belknap issue.

Right. And the Supreme Court has traditionally let the Senate do its own thing. So if the Senate picks Leahy to preside, the USSC would probably just let it be.
Heck, the USSC would probably be okay with the Senate picking Hillary Clinton to run the trial.
