Sorry, this makes this even more unconstitutional than it already is...
Senate Impeachment Trial must be presided over by the Chief Justice of the Supreme Court... You can’t substitute someone else... Sorry Dems...
Even more Banana Republic nonsense
No.
The Constitution says that the Chief Justice presides ONLY when the President is being tried. For all other impeachments, normal Senate rules apply.
The Chief Justice presiding is the exception to the rule, not the rule.
-PJ
Only if it is President of the United States.
Trump isn’t POTUS
If you look at the Belknap arguments you could make one that it relates back to when he was POTUS and thus Roberts should try it.
Unsettled area.
Maybe a Con lawyer expert on the Senate can chime in and say whether the Senate has the power to designate Roberts (even if he doesn’t want to do it)
