Howard Stern is challenging a lawsuit against his former executive assistant, Leslie Kuhn, who is seeking $2.5 million and a court order voiding her nondisclosure agreement. Stern alleges Kuhn attempted to extract a hush-money payment from him and his production company before they sued, and denies allegations of fostering a hostile work environment. Kuhn was fired for cause earlier this year due to an undisclosed reason, but claims it was due to pressure from an animal foster group operated by Stern's wife. If granted, Kuhn will be barred from disclosing personal information about Stern.
