O’Melveny Adds Former Justice Lawyer in White Collar Group (1)

Former Justice Department prosecutor David Harbach is joining O’Melveny & Myers’ white collar and corporate investigation practice after prosecuting war crimes at The Hague, the firm said Wednesday.

Harbach spent eight years as an assistant U.S. attorney in the Southern District of New York and in the Eastern District of Virginia. He served as special counsel to FBI Director James Comey from 2014 to 2015 and as a trial attorney in the public integrity section of Justice’s criminal division before that.

He most recently co-led investigations at The Hague into war crimes committed during the Kosovo conflict in the 1990s, an O’Melveny statement said.

His hire at O’Melveny’s D.C. office comes as the firm expanded into Texas in June with new offices in Dallas and Austin, while growing its tech-facing practice on the West Coast in tandem with much of Big Law. O’Melveny pulled in $835 billion in gross revenue last year, ranking it in the top 60 largest law firms in the country in 2020, according to American Lawyer.

The firm’s clients include Google, Samsung Display Co., Marvel, and ViacomCBS, according to the firm’s website.

O’Melveny lost counsel Matt Carter to McDermott Will & Emery last month. He was one of six lawyers that McDermott hired as partners in the firm’s transactions practice group.

Harbach has brought more than 35 cases to verdict in federal and state courts and conducted multiple high-profile public corruption trials, including those against former Sen. John Edwards (D-N.C.) and former Virginia Governor Robert F. McDonnell, according to the O’Melveny statement. He earned his law degree from Harvard Law School.

“David has prosecuted everything from complex white-collar and violent-crime cases to narcotics and RICO cases, including various financial fraud, corruption, and campaign-finance violations,” said Steven J. Olson, co-chair of O’Melveny’s white collar defense and corporate investigations practice, in the statement.
