In 1963, former postmaster general J. Edward Day left the administration of President John F. Kennedy to establish the firm's Washington, D.C. office.[10] Initial clients included the Advertising Mail Marketing Association.[11] The DC office later represented the American Medical Association, American Bar Association and the International Minerals & Chemical Corporation. The firm developed strengths in antitrust and the representation of clients in front of the Federal Trade Commission.

In 2001, the firm merged with Brown & Wood, a New York-based law firm established in 1914 with 400 attorneys and additional domestic offices in Washington, D.C., San Francisco and Los Angeles and overseas branches in London, Beijing and Hong Kong (where it practiced English law in addition to U.S. law). Brown & Wood was known for its securities, structured finance and securitization practices. Brown & Wood had offices in the World Trade Center on floors 54 and 56-59.[13]
