Baer was confirmed as the department's top antitrust lawyer in late December, almost a year after he was nominated for the post. As head of DOJ's Antitrust Division, he is responsible for policing both corporate mergers and any price-fixing schemes in the marketplace. For most of his career, Baer has shuttled between the public and private sectors. He has had two stints at the Federal Trade Commission, including leading its competition bureau in the late 1990s. He also headed the antitrust practice at Arnold & Porter before his appointment to DOJ. The Obama administration has reinvigorated antitrust oversight, most notably with the Justice Department's decision to sue to block the merger of AT&T and T-Mobile. The deal eventually unraveled. Baer is widely expected to run the division in the same aggressive tradition. During his tenure, he has already challenged Anheuser-Busch InBev's takeover of Grupo Modelo and pursued the government's case against Apple related to e-book pricing. He told the Senate during his confirmation process that he's been involved in fundraising for Bill Clinton, Al Gore, John Kerry, Hillary Rodham Clinton, and Barack Obama. The 63-year-old Wisconsin native received his undergraduate degree from Lawrence University and his law degree from Stanford University.
