Before joining the CFTC as a commissioner, Berkovitz served as a partner in the Washington, DC securities practice of WilmerHale, a global law firm with over 1000 attorneys in 14 offices. He joined the firm in September 2013 after serving for four years as general counsel of the Commodity Futures Trading Commission (CFTC).[3] During his tenure at the CFTC, Berkovitz was instrumental in the passage and implementation of rules related to the Dodd-Frank Act. He also served as the commission's deputy representative to the Financial Stability Oversight Council. Earlier, he served as counsel to the United States Senate Permanent Subcommittee on Investigations. During that time, he led several major investigations into oil markets and energy prices, including the role of financial speculation in natural gas and crude oil prices; the effect of the Department of Energy’s program to fill the Strategic Petroleum Reserve on oil prices and energy security; the effect of increasing concentration in the gasoline refining industry on retail gasoline prices; and allegations of illegal payments by American companies to Iraq during the United Nations Oil-for-Food program.[4] From 1995-2001, Berkovitz served as deputy assistant secretary for planning, policy, and budget in the Department of Energy’s environmental management program. He was responsible for formulating and presenting to Congress the Department’s $6 billion annual budget for the clean-up of nuclear and hazardous wastes generated by the production of nuclear weapons. Prior to that, he served as counsel to the Subcommittee on Nuclear Regulation of the Senate Committee on Environment and Public Works.[5] Berkovitz serves of an adjunct professor at Georgetown University Law School, where he teaches energy trading and regulation.
