Gary Condit revisited

A few years ago when Chandra Levy was found dead in Washington D.C, Congressman Gary Condit had to deal with a firestorm as allegations of an affair and possible implications in her murder were tossed about. The controversy eventually forced him from office, though no real evidence came out tying him to the crime. So can someone explain why a reporter flies to Arizona to knock on his door? What possible news value could there be unless there is new evidence or attempts to have him once again talk to the media prove fruitful?
