The Ohio Supreme Court is investigating possible misconduct by the attorney who first tipped Ohio State's then-football coach to NCAA violations by his players. Jim Tressel's decision not to alert university officials to the tip from lawyer Christopher Cicero ultimately led to Tressel's resignation under pressure for failing to report the violations. State Disciplinary Counsel Jonathan Coglin writes in a ruling that Cicero violated professional conduct rules by revealing information from interviews with a potential client. The filing cites three emails Cicero sent Tressel on April 2 and April 16.
