What’s the deal with Roberts not presiding?

[Speedy]

It’s because the Constitution doesn’t require the chief justice to preside in the trial of anyone but the sitting president. This gives Justice Roberts the option to intercede, along with the rest of the Trump Court, in the trial. The court will probably declare the Senate trial moot since Pres. Trump is no longer in office - just like they did with the emoluments suit which was shameful.
