President Trump wasn't invited to Rep. Lewis' funeral. It was the height of good manners for the President not to show.
IMHO, it would have been rude if Trump would ascended the pulpit to eulogize Lewis as a Tremendous American.
I agree and I can relate.
I had a manager / boss (he was white like me) and he was an ass hole. He got in a wreck and messed up his insides. He died several months later. He remained an ass hole to the end.
We were all given the time off to go to his viewing and funeral, if we wanted to. I chose NOT to be a hypocrite. So, I didn't go.
The company tried to doc my pay for not attending, even though it was (supposedly) voluntary.
Trump likely did the same.
Could he have played it better as a politician? Probably so.
However, I (for one) like it that he's a piss poor politician.
