I barely knew Donald Trump prior to his election campaign, pre-2020. Not as a business man nor media personality. I would probably recognize the name, but I wouldn't be familiar with anything he had done up until he ran for president the first time.
The only notable thing about him, for me, is that he was president (easily one of the worst), and he is a convicted felon. So, I think it's pretty stupid to argue whether "convicted felon" should be in his opening lede line for Wikipedia. To me, that answer is obvious. Yes, of course it should be.
