For the second time this year, Debevoise & Plimpton has come under scrutiny for the way it handled confidential witnesses amid an internal investigation into sexual misconduct. In the most recent incident, news reports have stated that confidential witnesses may have been compromised when a draft report on sexual misconduct allegations at CBS Corp. leaked to the press.

Debevoise’s Mary Jo White was tapped earlier this year, alongside Covington & Burling’s Nancy Kestenbaum, to conduct an internal investigation into alleged sexual misconduct on the part of former CEO Leslie Moonves, as first reported by The New Yorker, and former “60 Minutes” executive Jeff Fager. The findings of the investigation may play into a decision that CBS’s board is expected to make in January regarding whether Moonves was fired for cause—a determination that would impact whether he receives a potential $120 million severance package.
