O’Sullivan is a member of U.S. Secretary of State Antony Blinken’s Foreign Affairs Policy Board. Between 2004 and 2007, she was special assistant to President George W. Bush and was Deputy National Security Advisor for Iraq and Afghanistan during the last two years of her tenure. In 2013, O’Sullivan was the Vice Chair of the All Party Talks in Northern Ireland.

She is a Senior Director at the strategic consulting firm Macro Advisory Partners, and is the Chair of the North American Group of the Trilateral Commission.
