Following the attack on Sergei Skripal in Salisbury, UK on March 4, 2018, Russian TV network coverage of the incident named Goldfarb as the murderer of Alexander Litvinenko in 2006. Goldfarb sued two Russian TV channels, Channel One Russia and RT, for libel in US. The case is pending in US District Court for the Southern District of New York. On March 4, 2020, U.S. District Judge Valerie Caproni denied a motion to dismiss the case, ruling that New York had personal jurisdiction over the matter because Channel One Russia maintains a Manhattan studio where correspondent Zhanna Agalakova interviewed Goldfarb in relation to the allegedly defamatory story.
