Timothy Snyder is a history professor at Yale, and he’s curious why there’s all this talk about Sen. Majority Leader Mitch McConnell having any say over the shape of President Trump’s impeachment trial when it will be Chief Justice John Roberts presiding over it. Here’s his thread on the matter.

Yeah, we keep hearing that — which is why all of the senators running for the nomination in 2020 ought to be disqualified. They’ve already declared President Trump guilty on the debate stage, even before the articles of impeachment were written up.

So McConnell has disqualified himself, but Warren, Booker, Klobuchar, Sanders, and Harris haven’t?
