I still think the Senate’s response to any questions of impeachment is “what impeachment? the House has not delivered any Articles of Impeachment; nothing to discuss.” Once received, McConnell moves to begin trial _next_day_ (like 12:01 AM), with immediate dismissal if House Managers are not physically present.
The House has yet to name its managers and appropriate funds for the trial.
They should have passed the resolution concurrently with the articles of impeachment.
Nancy will probably move to do it once the Senate adopts its rules. There’s no real point in stalling indefinitely.
