A former Department of Justice official has rejoined Chadbourne & Parke in the firm’s Washington office, the firm announced Monday.
Keith Rosen, former chief of the Criminal Division in the U.S. attorney’s office for the District of Delaware has returned to Chadbourne as a counsel in the white collar defense, regulatory investigations and litigation group.
Rosen first joined the division in 1999. He joined Chadbourne in 2005 before returning to DOJ as chief of the division in 2007. During his time with the U.S. attorney, Rosen investigated financial institution and securities fraud, including insider trading, economic espionage and export violation matters.
During his second stint with the U.S. attorney’s office, Rosen said he spent three years investigating the manipulation of penny stocks by people around country whom were using illegal online promotional schemes. This was a coordinated effort with the Department of Homeland Security, the IRS and state and local police.
Rosen also investigated and prosecuted the head information technology officer of a Wilmington firm who used confidential client information to place trades ahead of mergers and acquisitions.
“Ultimately you’re dealing with one of the most significant types of breaches of trust when you’re dealing with the people overseeing the technology,” Rosen said. “It was a very eye-opening experience for the firm.”
At Chadbourne, Rosen will focus on building up the special investigations and white collar defense practice. In the past, Rosen has represented individual and corporate clients on tax evasion, securities fraud and deceptive trade practices.
Rosen said that his decision to return to the firm was made easier because of the opportunity to work with colleagues like Abbe Lowell and to be part of the expansion of the practice group.
“Keith’s unique combination of skills and experience will be welcome additions to our white collar practice,” Abbe Lowell, head of the firm’s white collar defense, regulatory investigations and litigation group, said in a statement.
