As far as I know many people did, I think you can do a quick search for it on X or Google. My instagram stories were filled with posts calling out Trump for how vile he is
Jack White, Whoopi Goldberg, Jimmy Kimmel, Josh Gad hit back at "disgusting, vile, egomaniac, loser, child" Donald Trump over Rob Reiner death comments also Maria Shriver, Patrick Schwarzenegger, The Obamas, Mick Foley, I think there were others too
Per NYP's own story Nick Reiner butted in the middle of Bill Hader talking to his friends at Conan's party, Bill was like "excuse me man this is a private conversation", and then Nick "stormed off". This doesn't seem important factoid to this story at all. Turning a mountain into a molehill here. Leave Bill alone.
