PITTSBORO, N.C. -- Firefighters are battling a major fire at a historic courthouse in North Carolina. Officials said Thursday that everyone was safely evacuated from the Chatham County courthouse. Smoke and flames billowed from the building nearly two hours after the blaze began. The courthouse in the middle of Pittsboro was built in 1881 and has recently been under renovation. County officials said they do not have specific information on the cause of the fire. The building has been the site of an ongoing dispute about a videotape purportedly showing former presidential candidate John Edwards in a sexual encounter. Superior Court Judge Abraham Penn Jones told The Associated Press on Thursday that the materials turned over in the case are in a vault away from the courthouse.
