The IRF Ambassador: A Key Component of U.S. Leadership on Religious Freedom

October 03, 2025

The U.S. Ambassador-at-Large for International Religious Freedom, often referred to as the IRF Ambassador, plays a vital role in the U.S. government’s promotion of international religious freedom. Pursuant to the International Religious Freedom Act of 1998 (IRFA), the IRF Ambassador is mandated to head the Office of International Religious Freedom, or IRF Office, at the State Department. Additional duties include serving as the principal adviser to the President and Secretary of State on matters involving religious freedom abroad and representing the United States on IRF matters diplomatically. In April, President Trump nominated Mark Walker as the next IRF Ambassador. As religious persecution increases globally, it is urgent that the Senate confirm an IRF ambassador to ensure this issue remains a priority in U.S. foreign policy and globally.  


On today’s episode of the USCIRF Spotlight Podcast, USCIRF Chair Hartzler and Vice Chair Mahmood speak with former IRF Ambassadors David Saperstein and Samuel Brownback to reflect on the impact of this position and share recommendations for the next Ambassador.
