Bill held several key positions in the DOJ’s Antitrust Division. Since 2011, he served as chief of the TEA Section, which is responsible for civil antitrust enforcement, competition advocacy and competition policy in areas such as domestic and international aviation, electricity, oil field services and agricultural commodities. He supervised the section’s investigations of mergers and civil non-merger antitrust violations, shaped substantive analyses, engaged with international antitrust authorities, presented matters to DOJ leadership and litigated enforcement actions. Bill served as assistant chief of the section from 2005 to 2011.

Under Bill’s supervision, the section handled many high-profile matters, including litigating merger cases (such as challenges to the American Airlines/US Airways, JBS/National Beef and National CineMedia/Screenvision deals), crafting settlements to resolve competition concerns arising in numerous investigations involving multi-billion dollar transactions and developing the legal precedent in the KeySpan and Morgan Stanley financial derivative cases for the use of disgorgement as a Sherman Act remedy.

Bill began his Antitrust Division career as a trial attorney in the Litigation III Section from 1998 through 2005. During that time, he was the lead staff attorney on numerous investigations, including several media merger reviews and was a key member of the successful trial, appellate and judgment compliance teams in United States v. Visa.

In 2001, he served on detail as a special assistant United States attorney in the Eastern District of Virginia, where he prosecuted felony and misdemeanor criminal violations. He began his legal career in the private sector as a litigation associate at another AmLaw 100 firm, where he handled private antitrust cases.
