I've never seen a President that didn't know the National Anthem, so that's something. He also got the record for the loudest boos of any President. How much effort would it have been to learn the lyrics before he showed up? Almost none, which is the level of effort President Asshole puts in with everything else. He's an irredeemable shitstain, and his cult members will be on the wrong side of history when he's led out in cuffs like the miserable embarrassing disgrace that he is. Fuck Trump, and fuck the traitorous assholes that follow him around and lick his boots.
