Rolling Stone is accusing a University of Virginia dean of leaking a confidential deposition video relating to a lawsuit against the magazine over a now-retracted article involving a gang-rape hoax at the school.

Lawyers for Rolling Stone, its publisher and the author of the article claim that dean Nicole Eramo, who is suing the magazine for defamation, leaked video of a deposition to ABC News to use in an upcoming “20/20” documentary of the case. The feature is supposed to air three days before the trial.
