There’s something oddly hypnotic in watching Piers Morgan interview Donald Trump on Airforce One. Despite a constant urge to scream at the TV, mute them or change channel, I can’t switch off. Two of the most reprehensible & inane characters on the planet, inarticulately putting the same points across. Piers avoiding asking any difficult questions; the President avoiding answering any of them. But I can’t switch off.
