Doesn't matter. If the Senate isn't in session to receive the charges/complaint, it sits until the Senate is available to receive it. And since a pro forma session doesn't involve outside business and is basically only for the Senate, meaning they're closed for everyone else, they won't be open until 1/19.

McConnell is still Senate Majority Leader until the inauguration. He needs a unanimous vote from the current Senate to convene for this, and Cruz alone will vote against it and shut it down.

Besides, even IF [they] were to accomplish the impossible like that, [they] would need to do it all before the close of business tomorrow evening. That ain't happening. There's no Earthly way [they] can "massage" the rules and laws like that.
