Greenberg Traurig shareholder Joel Katz, the founder of the firm’s entertainment practice and its Atlanta office, is fighting back against newly filed sexual harassment claims, with his lawyer saying Katz “categorically” denies the allegations.

Katz’ lawyer, Howard Weitzman of Los Angeles boutique Kinsella Weitzman Iser Kump & Aldisert, said in a statement that the Greenberg shareholder will cooperate in any investigation or lawsuit by “telling the absolute and whole truth.”
