Elizabeth Shackelford was a career diplomat in the U.S. State Department until December 2017, when she resigned in protest of the Trump administration. During her tenure with the Foreign Service, Shackelford served in the U.S. embassies in Warsaw, Poland, South Sudan, Somalia, and Washington, D.C. For her work in South Sudan during the outbreak of civil war, Shackelford received the Barbara Watson Award for Consular Excellence, the State Department's highest honor for consular work.

Her resignation letter to Secretary of State Rex Tillerson, first shared by Foreign Policy, went viral. Since her departure, Shackelford has continued to raise awareness about the consequences of our troubled diplomacy in the press, in academic and community groups, and through other public commentary.

As an independent consultant, Shackelford focuses on human rights advocacy, conflict mitigation, political affairs, and democratic processes. Born and raised in Mississippi, she now lives in Rochester, VT.
