Cynthia Littleton Business Editor The latest twist in the battle between UTA and former MediaLink chairman-CEO Michael Kassan is a defamation lawsuit filed by Kassan against UTA attorney Bryan Freedman. Kassan has sued Freedman for slander and libel stemming from a statement that the lawyer made earlier this week to Deadline, which is a sibling publication to Variety under Penske Media Corp. Kassan and UTA parted ways earlier this month amid a flurry of litigation and arbitration filings and heated accusations from both sides.
