But not a great deal of precedent. As far as this old lawyer can research the only official in the US impeached and tried after leaving office was William Belknap, who was Secretary of War for President Grant. In 1876 he was impeached by the House after he had resigned as Secretary. The articles of impeachment were based on corruption in prosecution of the Great Sioux War. Belknap was acquitted as they could not get a 2/3rd majority of the senate to agree that there was jurisdiction when an individual had left office prior to trial.
I have a hunch that there will be a problem getting a 2/3rd vote against Trump as some will consider the matter moot.
footnote: Grant replaced Belknap with Alphonso Taft as Secretary of War and later appointed Taft Attorney General. Taft was the father of later President William H Taft who after presidency became a justice of the US Supreme Court.
Yes. My post
#1,652 was in response to a claim that impeachment proceedings couldn't possibly continue against a retired President, and I was putting a case that it wasn't necessarily as simple as that. I also said that the prospect of passage of impeachment by the Senate seemed to me "highly doubtful" at present.
It was of course the Belknap 1876 case I was mainly thinking of. [I have read that judges have been impeached after resignation but as to what level of judge I would need to check.] Your account of Belknap differs however in one significant respect from what I had seen.
You say that Belknap was acquitted as they could not get a 2/3rd majority
on jurisdiction. If so , I agree that would be a very persuasive precedent against jurisdiction in the present case. I had read however that the Senate actually agreed on jurisdiction (which arguably might only need a simple majority??), and when it proceeded to a vote
on the merits there was a majority vote against Belknap on each count but each failed to reach the necessary 2/3rd majority. Example of source:
