Ms. Bean was first hired by Senator Levin in 1985 to serve as an attorney on the U.S. Senate Homeland Security and Governmental Affairs Committee. In 2003, Senator Levin appointed her Staff Director and Chief Counsel of the Committee's Permanent Subcommittee on Investigations, which he chaired.
During her 29-year tenure with Senator Levin, Ms. Bean handled a variety of complex investigations, hearings, and legislation, including matters involving money laundering, offshore tax abuse, foreign corruption, unfair credit card practices, corporate misconduct involving derivatives or structured finance, health care fraud, and shell companies with hidden owners. Investigations headed by Ms. Bean included inquiries into the 2008 financial crisis, HSBC money laundering problems, London whale trades at JPMorgan Chase, the collapse of Enron, and offshore tax avoidance by Apple, Microsoft, and Caterpillar. In 2014, Senator Levin retired from the Senate, and so did Ms. Bean.
Ms. Bean served as a law clerk to the former Chief Judge of the U.S. Claims Court, Alex Kozinski, who later served as the Chief Judge of the Ninth Circuit Court of Appeals. She also worked for two years as a trial attorney with the U.S. Department of Justice Civil Frauds Section.
In 2013 and 2011, the Washingtonian magazine named her one of Washington's 100 most powerful women. In 2010, Ms. Bean was selected by the National Law Journal as one of Washington's most influential women lawyers.
