CBS Corp. announced in a Securities and Exchange Commission filing that its chief legal officer will leave his post Friday.

Lawrence Tu, who tendered his resignation Feb. 22, will remain with the company as a senior adviser to acting CEO Joseph Ianniello until April 30, according to the filing. Tu will officially leave the company a month shy of the end of his latest contract with CBS. According to an SEC filing dated July 24, 2017, Tu's base salary increased to $1.35 million.

A spokesperson for CBS confirmed to Law.com that Laura Franco, a longtime member of the CBS in-house legal team, will take over as the company's executive vice president and general counsel on March 1.

Tu and Franco were not made available for comment.

Tu was hired by the company's former CEO, Les Moonves, who was ousted from CBS last year after several employees accused him of sexual harassment. Following the allegation, CBS hired Covington & Burling and Debevoise & Plimpton to investigate the allegations. Debevoise & Plimpton came under scrutiny after a draft of its findings was leaked to the press in December. According to a person with knowledge of the situation, the findings of the events were not leaked by Debevoise. The report was leaked to The New York Times and indicated that Moonves engaged in “transactional” oral sex with CBS employees. At the time, the company indicated that it was worried about the legal ramifications of the draft becoming public because CBS employees who participated in the report were promised confidentiality.

According to his profile on the CBS Corporation's investor relations website, Tu joined CBS in 2014 when he replaced longtime general counsel Louis Briskman. Before joining CBS, Tu worked as the general counsel of Dell and before that served as the general counsel of NBCUniversal Media LLC for three years. During his time at NBC, Tu oversaw the acquisition of Telemundo, Bravo and Universal. He has also worked as co-general counsel of Goldman Sachs Asia South Pacific where he worked out of the company's Hong Kong offices.

Tu practiced at O'Melveny & Myers in New York for 15 years before going in-house. After graduating from Harvard Law School, Tu served as a clerk for U.S. Supreme Court Justice Thurgood Marshall and Judge Walter Mansfield of the U.S. Court of Appeals for the Second Circuit.

According to her LinkedIn profile, Franco joined CBS in 1995. She most recently served as executive president and associate general counsel for CBS. She was responsible for handling mergers and acquisitions, cable distribution and other company-wide transactions. Franco is also a graduate of Harvard Law School.
