Keith M. Rosen Expands White Collar Defense, Regulatory Investigations and Litigation Group

New York, NY – February 27, 2012 – The international law firm of Chadbourne & Parke LLP announced today that Keith M. Rosen, Chief of the Criminal Division in the United States Attorney’s Office for the District of Delaware, has rejoined the Firm’s White Collar Defense, Regulatory Investigations and Litigation Group as Counsel in the Washington, D.C. office.

Mr. Rosen first joined the Criminal Division in the District of Delaware in 1999, and has over ten years of trial and appellate litigation experience. He has worked extensively on investigations involving financial institution fraud and securities fraud, including insider trading, as well as economic espionage and export violation matters. He has lectured on topics including market manipulation in the over-the-counter securities markets, and has been a participant in the Department of Justice Securities and Commodities Fraud Working Group.

Mr. Rosen initially came to Chadbourne from the DOJ in 2005, and spent approximately two years with the firm until returning to the DOJ in 2007 as Chief of the Delaware U.S. Attorney’s Office Criminal Division. He is returning now to Chadbourne to focus on building a national Special Investigations and White Collar Defense practice. During his prior tenure at the firm, Mr. Rosen represented individual and corporate clients on matters involving allegations of tax evasion, securities fraud and deceptive trade practices.

“Keith’s unique combination of skills and experience will be welcome additions to our white collar practice,” said Abbe Lowell, head of Chadbourne’s White Collar Defense, Regulatory Investigations and Litigation group. “His civil litigation capabilities, particularly with respect to representing corporate and individual clients in complex civil litigation matters, enhance Chadbourne’s already outstanding team of trial lawyers. I thoroughly enjoyed working with Keith and I am glad to have him back in our practice.”

“We are proud to welcome Keith back to the firm,” said Mary Lopatto, Managing Partner of Chadbourne’s Washington D.C. office, “as we continue to develop our special investigations practice and build upon our reputation as a market leader in the field. It is a pleasure to see a colleague like Keith at Chadbourne again.”

Andrew Giaccia, Chadbourne Managing Partner, added, “Keith’s exceptional background in multi-agency and multi-jurisdictional criminal investigations will be a great asset to the Firm and will complement our nationally and internationally recognized white collar criminal defense practice. On a personal level, we missed Keith when he was away and we are delighted that he has returned to Chadbourne.”

Chadbourne’s White Collar Defense, Regulatory Investigations and Litigation practice counsels and represents clients (including companies, government officials, corporate directors, officers and other professionals) in connection with a wide range of matters, including criminal investigations and defense, congressional investigations, internal investigations, federal agency (SEC, IRS, FTC) cases, inspector general investigations, state attorney general investigations and parallel proceedings.

Mr. Rosen is a graduate of Brown University where he earned an A.B., magna cum laude. He received his J.D. from Yale Law School, where he was a senior editor for the Law Review. Following Law School, Mr. Rosen served as a law clerk to the Hon. Edward R. Becker, United States Court of Appeals, Third Circuit, and was then an associate at Morgan, Lewis & Bockius LLP.
