Edwards Cancels Speech at Hofstra University

Former Democratic presidential candidate John Edwards has canceled a speech at Hofstra University in New York.

The school's announcement Thursday extends an exile for the former North Carolina senator that began last month after he admitted to an extramarital affair.

Edwards had been scheduled to speak at Hofstra on Tuesday. School spokesman Stuart Vincent says an agent for John Edwards did not say why the speech was canceled.

John Edwards hasn't spoken publicly since admitting to an affair about a month ago. While both John and Elizabeth Edwards still have speeches scheduled in September and October, they have been slowly canceling events.

Edwards acknowledged last month that he had an affair with Rielle Hunter, who was hired to produce videos of him in 2006.
