I see that Mr. Hans Moleman has just posted a wry reflection on the race to impeach nearly ex-President Trump before he leaves town. Hans (I call him Hans because we are good friends) calls this “the Cadaver Impeachment”, referring to the Cadaver Synod that tried and condemned the rotting corpse of former Pope Formosius, in the ninth century AD. They also repealed all his acts, including his ordinations of bishops.
You can read it at mistermoleman.com. Hans doesn’t post very often these days (he’s quite old), but when he does it is worth a look.
