ACLU, Halperin, along with Jerry Berman, also at the ACLU, worked with President Reagan's CIA Director William Casey to agree on language in the Intelligence Identities Protection Act of 1982, which has successfully protected journalists publishing the names of covert agents. He also worked on a number of civil rights bills, including an immigration reform bill in 1986, the Civil Rights Restoration Act of 1987, and the American Disabilities Act of 1990.

Clinton administration At the start of the Clinton administration, Halperin was appointed as a consultant to the Secretary of Defense and the Under Secretary of Defense for Policy (1993). In 1994 President Clinton nominated Halperin for the position of assistant secretary of defense for democracy and peacekeeping, and was opposed by the Senate Armed Services Committee which supplied a detailed list of Halperin's activities and stated views which it regarded as incompatible with his appointment. Clinton then named him to be a Special Assistant to the President and Senior Director for Democracy at the National Security Council (1994–1996). Secretary of State Madeleine Albright appointed him to the position of Director of Policy Planning at the State Department (1998–2001) in Clinton's second term. Halperin focused on several issues of interest to Secretary Albright, including democracy promotion (the Community of Democracies and inauguration of the four priority democracies); nuclear issues; a review of the way that the United States responds to humanitarian disasters overseas; and northeast Asian security. He also was integrally involved in managing the crises in Kosovo and East Timor.

He was the director of the Washington office for the Open Society Institute (now the Open Society Foundations) from 2002 to 2005 and the director of U.S. advocacy from 2005 to 2008. He was the executive director of the Open Society Policy Center from 2002 to 2008. He also was a senior vice president at the Center for American Progress from 2003 to 2005 and a senior fellow
