He oversaw nine bureaus and offices led by Senate-confirmed principals, with 1,300 employees and a combined foreign assistance budget of more than $5 billion annually, and the mission of preventing and countering threats to civilian security, including terrorism, mass atrocities, and violations of human rights and the rule of law.
Concurrently, Ambassador Sales was Ambassador-at-Large and Coordinator for Counterterrorism. After being nominated by the President and unanimously confirmed by the U.S. Senate, he was sworn in on August 10, 2017.
