With wide-ranging experience working on national security issues in the White House, the State Department, and the U.S. Senate and House of Representatives, Stephen Rademaker helps clients navigate international policy, sanctions, and CFIUS challenges.

Among his accomplishments in public service, Stephen had lead responsibility, as a U.S. House staffer, for drafting the legislation that created the U.S. Department of Homeland Security. Serving as an Assistant Secretary of State from 2002 through 2006, he headed at various times three bureaus of the State Department, including the Bureau of Arms Control and the Bureau of International Security and Nonproliferation. He directed the Proliferation Security Initiative, as well as nonproliferation policy toward Iran and North Korea, and led strategic dialogues with Russia, China, India, and Pakistan. He also headed U.S. delegations to numerous international conferences, including the 2005 Review Conference of the Parties to the Treaty on the Nonproliferation of Nuclear Weapons.

Stephen concluded his government career on Capitol Hill in 2007, serving as Senior Counsel and Policy Director for National Security Affairs for then-Senate Majority Leader Bill Frist (R-TN). In this role, he helped manage all aspects of the legislative process relating to foreign policy, defense, intelligence and national security. He earlier served as Chief Counsel for the House Select Committee on Homeland Security of the U.S. House of Representatives and as Deputy Staff Director and Chief Counsel of the House Committee on International Relations.

During President George H. W. Bush’s administration, Stephen served as General Counsel of the Peace Corps, Associate Counsel to the President in the Office of White House Counsel, and as Deputy Legal Adviser to the National Security Council. After leaving government in 2007, he continued to serve as the U.S. representative on the United Nations Secretary-General’s Advisory Board on Disarmament Matters, and he was subsequently appointed by House Republican Leader John Boehner (R-OH) to the U.S. Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism.

In addition to his practice at Covington, Stephen is an adjunct assistant professor at Georgetown University, where he teaches a course on Sanctions in U.S. Foreign Policy in the Security Studies Program of the School of Foreign Service.
