Some months ago, Nona Summers was invited to a charity lunch at a grand clifftop house in Malibu. The first person she met was the television producer Mark Burnett (who is behind more than 100 shows, including The Voice and The Apprentice).

On hearing his name, Nona said: “You should be ashamed of yourself. If it weren’t for you promoting and coddling a bankrupt real-estate shyster, and never admitting what he was really like, keeping quiet for your own ends, we would not have this blustering, dangerous coward in the White House.”
