At the outset!
The irony here is Madame Antoinette's reliance on Belknap post-resignation trial, who was a hero of Republican Reconstruction and had prosecuted the KKK. Driven them from the Army.
The Senate trial devolved into an imbroglio where no less than Custer pointed fingers at Belknap AND US Grant's brother Orvil (for a no-work cartography contract from Interior).
She wants Trump in the stocks, it ain't never gonna happen. Trump has what Belknap never had - presidential immunity.
Unless Miotch wises up and whips his caucus into an immediate Dismissal, what's gonna happen is that SCOTUS and no less than Queeg Roberts will be forced to address the immunity 'gap' between Nixon v. Fitzgerald and Clinton v. Jones.
Interesting - and great history!
And it’s true that Roberts may have to get real and actually act like a Chief Justice.
