Joseph I. Lieberman is Senior Council to Kasowitz Benson Torres & Friedman LLP. Prior to joining Kasowitz, Senator Lieberman, the Democratic Vice-Presidential candidate in 2000, served 24 years in the United States Senate, retiring in January 2013 following the end of his fourth term. During his tenure, Senator Lieberman helped shape legislation in virtually every major area of public policy including national and homeland security, foreign policy, fiscal policy, environmental protection, human rights, health care, trade, energy, cybersecurity and taxes. He served in many leadership roles including as Chairman of the Committee on Homeland Security and Government Affairs, which is the Senate's major oversight and investigative committee. On that Committee, Senator Lieberman led numerous congressional investigations, including investigations into Enron’s collapse, the federal government’s response to Hurricane Katrina, the Fort Hood mass shooting, and most recently the deadly attack in Benghazi, Libya.

Prior to being elected to the Senate, Senator Lieberman served as the Attorney General of the State of Connecticut for six years. He also served 10 years in the Connecticut State Senate, including three terms as majority leader.

Senator Lieberman is the recipient of numerous awards and recognitions, and in 2012, he received the Ewald von Kleist Award, which is given to the individual who has “made an outstanding contribution to peace and conflict resolution,” by the Munich Security Conference, the most prominent independent forum for the exchange of views by international security policy decision-makers. That year the Republic of Korea also awarded him the Order of Diplomatic Service Merit Gwanghwa Medal.

In addition to practicing law, Senator Lieberman is a Co-Chair of the American Enterprise Institute’s American Internationalism Project, which is a cross-party initiative designed to rebuild and reshape a bipartisan consensus around American global leadership and engagement.
