Welcome to Ukraine Oversight

Since Russia's full-scale invasion of Ukraine in February 2022, 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 projects and recommendations. That collaboration continued 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 February 11, 2025, Special IG for OAR released the fifth quarterly report on OAR for the period October 1, 2024, through December 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, U.S. military activity in Europe, and other U.S. Government operations related to Ukraine response efforts.

We will continue to update this website with the latest information on independent oversight of the United States' Ukraine response.
