Welcome to Ukraine Oversight



The federal oversight community recognized early on that the U.S. government's Ukraine response is bigger than any one department or agency. We have been working together to deliver the whole-of-government, independent oversight that the scale, speed and scope of the Ukraine response effort requires.


On February 24, 2022, Russian military forces launched a full-scale invasion of Ukraine. The ensuing conflict has grown to become the largest land war in Europe since the end of World War II, leaving hundreds of thousands of casualties on both sides and displacing tens of millions of Ukrainian civilians from their homes.
The United States and the international community responded quickly and forcefully to this aggression. More than 50 nations have provided support to Ukraine, of which the United States is the largest single donor.  As of May 2024, the U.S. Congress has appropriated $174.2 billion for the U.S. response to Russia’s full-scale invasion of Ukraine.
Since the time of the full-scale invasion, more than 20 oversight entities from across the Federal Government have worked closely together on the Ukraine Oversight Interagency Working Group, to ensure a timely, collaborative, and comprehensive approach to the whole-of-government oversight. That collaboration continued as, following the Department of Defense’s declaration of the overseas contingency Operation Atlantic Resolve (OAR), the DoD IG was named Lead Inspector General for OAR by the Council of the Inspectors General on Integrity and Efficiency Chair effective in October 2023. In December 2023, Congress re-designated the Lead IG as the Special Inspector General for OAR with additional responsibilities and reporting requirements regarding Ukraine oversight.
On May 16, 2024, Special IG for OAR released the second quarterly report on OAR for the period January 1, 2024, through March 31, 2024, which provides a detailed look at U.S. security, economic, and humanitarian assistance to Ukraine and regional allies, financial support to Ukraine’s government, increased U.S. military activity in Europe, and other U.S. Government operations related to Ukraine response efforts.
In January 2023, the leaders of the DoD, State, and USAID OIGs traveled to Ukraine and other nations in the region to gain a fuller understanding of the situation on the ground. They returned to Ukraine in January 2024 to obtain a first-hand update from U.S. and Ukrainian officials, to cement relationships with key oversight and anticorruption entities in Ukraine, and to visit sites where we were able to observe the administration and impact of U.S. assistance and understand the risks and challenges in these programs. In meetings with U.S. and Ukrainian senior officials, DoD, State and USAID IGs expressed the importance of accountability and transparency regarding such assistance, including the expectation that OIG personnel—now working on the ground out of the U.S. Embassy in Kyiv – will be promptly notified of allegations that U.S. funds and equipment have been misused or subjected to other misconduct.
We will continue to update this website with the latest information on independent oversight of the United States' Ukraine response.
