News Corp is in discussions with D.C. attorney Gerson Zweifach as its new general counsel, Bloomberg reported late this afternoon. Whoever takes the job could assume a crucial role for News Corp as investigations and Parliamentary testimony continue in the U.K. phone-hacking scandal. During his more than 29 years at Williams & Connolly LLP, Zweifach has trial experience in a wide variety of legal areas including antitrust, securities, libel and commercial cases, according to the firm’s website. There have been at least 21 arrests in fallout from the News of the World case including a female police officer who was picked up and released this week. News Corp board member Joel Klein is overseeing the company’s internal investigation of its journalists’ behavior. Zweifach would replace Lawrence Jacobs, who left in June. Some at the company say Jacobs quit because he felt Klein was encroaching on his turf. News International subsidiary board menber Janet Nova has been serving as interim general counsel.
