The Houston Chronicle reports the nature of the evidence is not disclosed in a federal court motion filed last week by Skilling's attorney, Daniel Petrocelli. The lawyer is seeking more time for an appeal of Skilling's conviction and prison term related to the 2001 implosion of the former Houston-based energy giant.
Skilling already has lost other appeals at the U.S. Supreme Court. He's serving 24 years in federal prison although a federal appeals court has ruled sentencing guidelines improperly were applied in his case. That could mean an eventual reduction in his prison time.
U.S District Judge Sim Lake, who presided over Skilling's trial, is to hold a hearing June 7.
