The Disclosures Tribunal heard Mr Kean had been briefed negatively about both men by garda commissioner Martin Callinan the day before he appeared on the Marian Finucane radio show, during which the remarks were made.
Mr Kean told the tribunal Mr Callinan had told him the whistleblowers had not co-operated with an internal garda investigation and that both had broken data protection laws.
Neither of these statements were based on fact and led to legal proceedings being taken by Mr McCabe and Mr Wilson.
Theunderstands RTÉ settled the actions with the payment of over €180,000. The station had no comment to make.
