Renata Hesse ’90 has been named acting head of the U.S. Justice Department’s Antitrust Division. She previously led the department’s Networks and Technology Enforcement Section, but left to become partner at Wilson Sonsini Goodrich & Rosati’s Washington, D.C. office. Hesse returned to the agency in March 2012 as special adviser for civil enforcement and deputy assistant attorney general for criminal and civil operations. Last year, while at Wilson Sonsini, she oversaw a Federal Communications Commission (FCC) review of AT&T’s $39 billion bid to buy T-Mobile. FCC and Justice Department opposition forced the companies to abandon the deal.
