Karen L. Dunn is a partner in the firm’s Washington, DC office.  Her practice focuses on high-profile civil and criminal litigation as well as strategic counseling and crisis management.  She has been recognized for her work by The National Law Journal (Click here), (Click here), The Washington Post (Click here), Law360 (Click here) and as Litigator of the Week by The American Lawyer and Global Competition Review. (Click here) (Click here).  In 2015, Ms. Dunn was named one of The National Law Journal’s Outstanding Women Lawyers (Click here). Within the span of one year, Ms. Dunn, together with BSF partner Bill Isaacson, won significant jury verdicts for two of America’s top technology companies. Recent representative matters include: 

  • Serving as co-lead trial counsel in a three and a half week jury trial in the District of Nevada for Oracle, which resulted in a $50 million verdict for software copyright infringement and state law violations.
  • Serving as co-lead trial counsel in a high profile antitrust case in the portable music industry, winning a defense verdict from the jury in a class action seeking $350M in damages before trebling.
  • Providing strategic and legal counsel to C-suite executives and in-house counsel at a large, multi-national company confronting simultaneous federal and state investigations, litigation, congressional inquiries, and media scrutiny.
  • Representing a target of the investigation by the House Committee on Oversight and Government Reform into political targeting by the IRS.
  • Serving as co-lead counsel, pro bono, in a lawsuit brought by the District of Columbia Council against Mayor Vincent Gray to enforce the Local Budget Autonomy Act.
  • Preparing witnesses and political figures for high-stakes testimony, congressional hearings and public appearances.

Prior to joining the firm, Ms. Dunn served in all three branches of government.  She worked in the White House as Associate Counsel to President Barack Obama, in the Eastern District of Virginia as an Assistant United States Attorney, in the Senate as communications director and a senior advisor to Hillary Rodham Clinton, and as a law clerk first to Judge Merrick B. Garland of the United States Court of Appeals for the DC Circuit and then to Justice Stephen G. Breyer of the Supreme Court of the United States.

Ms. Dunn has substantial trial and investigations experience. In addition to her work at the firm, as an Assistant United States Attorney, Ms. Dunn tried to jury verdict a number of multi-defendant cases, handled appellate briefing, and led complex investigations, often involving multiple government agencies. Ms. Dunn prosecuted a range of offenses including terrorism, international narcotics, money laundering, espionage, and fraud. In the White House, she represented the Executive Office of the President in congressional investigations and conducted internal investigations.  

Ms. Dunn is also expert in strategic counseling and crisis management. Throughout her career, Ms. Dunn has acted in public-facing and government-facing roles in which she was responsible for managing the response to developing crises. As a senior advisor and communications director to then-Senator Clinton, Ms. Dunn guided the response to a string of closely watched events, including those associated with rebuilding New York after 9/11. She has appeared on network and cable television, dealt with nearly every national news organization in America, and provided government officials and political candidates with strategic and communications advice.  She also employed her crisis management skills at the White House and in several high profile political campaigns, including the 2008 and 2012 presidential races.  Ms. Dunn has also been an occasional consultant to the television show, House of Cards. And she is a member of the Advisory Board to JerseyOn, a New Jersey non-profit that helps provide low-income students with access to high-speed broadband.

Ms. Dunn's unusual combination of experience-litigation and crisis management-enables her to help clients confront high-stakes legal problems that require them to simultaneously contend with the law, the media, and the government.  She has prepared high-profile political candidates, including President Obama, for televised debates and numerous nominees for high-stakes congressional hearings, including developing the confirmation strategy for now-Supreme Court Justice Sonia Sotomayor.  In the White House, Ms. Dunn advised the President and Executive Branch staff on a wide variety of constitutional, statutory, policy, and regulatory issues.  And she has guided companies, research universities, and non-profit organizations in crafting internal and external strategies designed to advance their policy goals.
