“I am delighted to welcome Rebecca back to our Studies Program,” said CFR President Michael Froman. “Rebecca’s extensive national security experience and deep understanding of grand strategy will bolster the Council’s efforts to provide policymakers with rigorous, independent analysis on the key foreign policy issues facing the United States.” 

Lissner most recently served as deputy assistant to the president and principal deputy national security advisor to the vice president in the Biden-Harris administration, counseling Vice President Kamala Harris and senior White House leadership on a range of national security and foreign policy matters. As a frequent participant in meetings with cabinet members and their deputies, she helped shape the administration’s crisis response and strategic decision-making on a wide range of issues including U.S.-China competition, the Russia-Ukraine war, artificial intelligence, and defense policy. Lissner participated in and helped prepare the vice president for meetings and international summits with world leaders and heads of state, and she frequently led diplomatic engagements with her foreign counterparts. As one of Harris’s chief foreign policy advisors, Lissner also helped shape the vice president and Democratic nominee for president’s messaging on national security and foreign policy. 

Previously, Lissner served as acting senior director and director for strategic planning on the National Security Council. In this capacity, she shaped the Biden-Harris administration’s foreign policy vision as a lead author of the Biden-Harris administration’s National Security Strategy and directed the Russia-Ukraine Tiger Team contingency planning process during Russia’s invasion of Ukraine. She served as a foreign policy advisor to the Biden and Harris campaigns during the 2020 election and advised Hillary Clinton’s campaign and presidential transition team during the 2016 election. During the Barack Obama administration, she served as special advisor to the deputy secretary at the U.S. Department of Energy.
