King & Spalding announced in recent days that a 32-year veteran of the antitrust division of the U.S. Department of Justice Donna N. Kooperstein has joined the firm as senior counsel in Washington, D.C.

She joins King & Spalding’s antitrust practice from the Department of Justice. There, she most recently served as chief of the antitrust division’s transportation, energy and agriculture section.


Jeffrey S. Spigel, leader of King & Spalding’s antitrust practice was quoted as saying in a press release at the firm’s website: “Donna’s tenure at the Justice Department and her extensive experience handling antitrust matters related to the transportation, energy and agriculture sectors give our practice additional depth and increase our capacity to help our clients in their antitrust matters in general and especially in DOJ-related matters. We are pleased to welcome Donna to our team.”

At the Department of Justice, Kooperstein supervised numerous high-profile matters, including the litigation challenging JBS’s proposed acquisition of National Beef; the successful effort in the KeySpan financial derivative case to obtain judicial endorsement of disgorgement as a Sherman Act remedy; and the lawsuit and settlement involving the proposed $27 billion Exelon/Public Service Enterprise Group electricity merger. As well, she played a major role in the department’s civil price-fixing suit against the major domestic airlines, U.S. v. Airline Tariff Publishing Co. In addition, Kooperstein supervised numerous investigations and cases in the oilfield services, agricultural biotech, railroad and maritime sectors, as well as the department’s competition advocacy activities before the Department of Transportation, Federal Energy Regulatory Commission and Federal Maritime Commission.

Kooperstein earned her J.D. degree, with high honors, from Rutgers University School of Law, and a B.A. degree from the University of Michigan.
