Three North Carolina doctors called on John McCain to release his health records.

In a conference call organized by a liberal movie company this afternoon, Dr. Wolfgang Liedtke of Duke University, Dr. Don Richardson of Brevard and Dr. Susan Murphy of Boone said that the Republican presidential candidate needed to share more information about his health.

In late May, about 20 reporters were allowed to look at McCain's records for about three hours.

But Liedtke, a clinical neurologist, said he still had questions about the severity of McCain's skin cancers and his vascular health, based on reports that the Arizona senator takes a daily aspirin to prevent blood clots and Ambien CR for insomnia.

"Somebody who is on Ambien that is not someone you do not want to take the 3 a.m. call because you might not be able to wake them up," he said.

He said Democrat Barack Obama should release all of his records as well, citing concern over the Illinois senator's history of smoking.

Brave New Films, which sponsored the call, has also created videos and a Web site featuring the signatures of 2,872 doctors calling for the records to be released.
