In news from the campaign trail, Republican presidential candidate Donald Trump has issued a scathing critique of rival front-runner Ben Carson. During a speech in Iowa, Trump seized on passages from Carson’s autobiography, in which the retired neurosurgeon describes himself as pathological.

Donald Trump: “If you’re pathological, there’s no cure for that, folks. OK? There’s no cure for that. And I did one of the shows today, and I don’t want to say what I said, but I’ll tell you anyway. I said that if you’re a child molester, a sick puppy, you’re a child molester, there’s no cure for that. There’s only one cure. We don’t to talk about that cure. That’s the ultimate cure. No, there’s two: There’s death and the other thing. But if you’re a child molester, there’s no cure. They can’t stop you. Pathological, there’s no cure. Now, he said he was pathological. OK.”
