In statutory interpretation, the use of the term "and" here implies removal from office, prohibition from future office holding, or both. If it said "or" it would be one or the other, period. And, to be clear, I'm a criminal/family law/probate lawyer, not a Constitutional specialist, and I have no experience with impeachment.
You are an attorney and I'm not but, as I posted, as a building inspector I deal with regulatory language on a daily, on-going basis. Prior to COVID-19 we all took an all-day class every year run by the chief prosecutor from the AG's office section that deals with building code issues. And her instructions have always been the same, year after year: "and" means "and" -- "or" means one "or" the other.
It's like the Second Amendment. The 2A only grants ONE right -- a right to keep AND bear arms. They are inseparable. It's not one right to keep, and a separate right to bear.
I remain firmly of the opinion and conviction that the current impeachment trial is unconstitutional and illegal. Trump was still in office when the House voted to impeach, so that was
technically constitutional -- even though it was an obviously bogus, manufactured charge with no basis in fact or evidence. However, once Trump left office, the process became moot. You can't remove from office someone who does not hold office.
