On a tour to promote his newly published biography of Franklin D Roosevelt, Black snapped at his media critics, saying: "I urge you, no matter how addicted you are to representing me as having been shamed, disgraced, and chased out as a scoundrel, to contemplate the possibility that there's just a chance that I might be innocent. As time will prove, I am."
The London Guardian said Black told reporters there had been "no concealment and total co-operation" with securities regulators investigating the allegedly unauthorized payments made to him and other senior Hollinger executives.
Meanwhile, Chris Browne, managing director of Tweedy Browne, Hollinger International's second largest shareholder, which sparked the internal investigation that led to Black's resignation, has called for an additional $200 million be returned to shareholders.
