The lead negotiator and spokesman for the NBA's referees says Tim Donaghy made threats against him, and says the disgraced former official's accusations about his colleagues shouldn't be believed because he is a "compulsive liar."

Lamell McMorris also says this was a difficult week for the referees union, with Donaghy appearing on "60 Minutes" and ESPN to give interviews to coincide with the release of his book. They included claims of misconduct among officials that Donaghy had made previously. But McMorris said that all officials cooperated in league and federal investigations.
