Early life and education

John J. Sullivan was born in 1959 in Boston, Massachusetts. He pursued his undergraduate education at Harvard College, graduating with a Bachelor of Arts degree. He then attended Columbia Law School, where he earned his Juris Doctor degree. His legal education provided a foundation for his subsequent career in both government service and private practice, focusing on complex litigation and regulatory affairs.

Legal and early political career

Following law school, Sullivan began his legal career as an associate at the law firm Mayer Brown in Washington, D.C.. He later served as a law clerk for Judge David B. Sentelle of the United States Court of Appeals for the District of Columbia Circuit. His early government service included roles in the George H. W. Bush administration, where he worked in the office of the White House Counsel. During the administration of George W. Bush, Sullivan held several significant positions, including Deputy General Counsel at the United States Department of Commerce and later as the department's General Counsel, advising on major international trade and regulatory issues.

United States Deputy Secretary of State

Sullivan was nominated by President Donald Trump and confirmed by the United States Senate as the United States Deputy Secretary of State in May 2017. He served under Secretaries of State Rex Tillerson and Mike Pompeo, acting as the chief operating officer of the United States Department of State. In this role, he managed day-to-day department operations and played a key part in implementing foreign policy initiatives, including engagements with NATO allies and partners in the Indo-Pacific region.
