I don't understand why you're getting down-voted. Living abroad and have stopped listening to news since the Trump election. Every 6 months I tune in, and while it seems a lot has happened, no progress has actually been made
this seems cool, but... so what? cute photo op and a tale for the grandkids....
There's a pretty trivial rule for getting this right. Phrase your sentence using who/whom as a question. Respond with he/him. If your response contains a "he", your initial statement should be "who"; if it contains a "him" then you're looking at a "whom" use.
