Overview

Mark Andrew Green (born June 1, 1960) is an American public official and member of the Republican Party. Over several decades he has held elected office, diplomatic posts and leadership roles in organizations focused on democracy promotion and international development. His career spans state and federal legislatures, a diplomatic assignment in East Africa, a presidency of a non‑governmental institute, and service as head of the United States Agency for International Development.

Political and legislative background

Green began his elected career in Wisconsin. He served in the Wisconsin State Assembly from 1993 until 1999, where he was involved in state policy and constituent services. In 1999 he won election to the U.S. House of Representatives and represented Wisconsin's 8th congressional district until 2007. While in Congress he served multiple terms and worked on issues typical of a Midwestern district representative, including economic and regional concerns. For details about his congressional service see his public record in the House: U.S. House profile, and information about the district he represented: Wisconsin's 8th congressional district.

Candidacy and transition to diplomacy

In 2006 Green sought higher office and ran for Governor of Wisconsin. That campaign ended without victory, and he subsequently left elected office. Shortly after the 2006 campaign he moved into diplomatic service: he was appointed United States Ambassador to Tanzania and served in Dar es Salaam from August 2007 until January 2009. His ambassadorship marked a transition from domestic politics to overseas diplomacy and development work; it also broadened his experience with bilateral and multilateral programs.

International development and organizational leadership

After his time as ambassador, Green took leadership roles in organizations concerned with democracy promotion and development. In 2014 he became president of the International Republican Institute, an organization that works to advance democratic processes abroad. He has also served on the board of directors of the Millennium Challenge Corporation, a U.S. foreign aid agency that implements development compacts with low‑ and middle‑income countries. These positions positioned him at the intersection of policy, program implementation and international partnerships.

Administrator of USAID

On May 10, 2017, President Donald J. Trump nominated Green to lead the United States Agency for International Development. Following Senate confirmation on August 3, 2017, Green was sworn in as USAID Administrator on August 7, 2017. He led the agency until his resignation in April 2020. During his tenure he oversaw U.S. civilian foreign assistance programs that include humanitarian aid, development assistance, and support for democratic institutions.
