The libel suit was filed by a Russian technology mogul, who argued that the news outlet defamed him when it published the dossier. BuzzFeed prevailed in the suit in December, when a judge found the organization had the right to publish the dossier. In response to a request from the New York Times, the judge last week unsealed documents related to the suit, including Kramer's deposition, which is why the topic is again back in the news.
