Our Team
Former Commissioner
Senator Joe Lieberman

All of us at the Commission are in shock and are heartbroken at news that Senator Lieberman has died suddenly and unexpectedly. Our thoughts and prayers are with his wife, Hadassah, their children, and extended family.

We all were the beneficiaries of Joe’s many years of selfless public service, his kindness, and civility. Joe was the definition of a Mensch – a person of great integrity and honor. He always put others first and always worked to better our nation, to which he tirelessly devoted so much of his energy. He had an indefatigable spirit that always pushed our work forward.

For nearly ten years, Joe was my co-chair here at the Bipartisan Commission on Biodefense. He cared deeply about the mission, for sure. Even more, he cared about each of our fellow Commissioners and the staff, all of whom I know are personally grieving at this tremendous loss. May his memory be a blessing.
