This was stated at a special meeting in the US Senate on Wednesday by Nicole Angarella, Acting Inspector General of the US Agency for International Development (USAID), according to European Pravda.
According to the USAID representative, since the beginning of the full-scale invasion, the United States has established a multi-level system of control over American assistance to Ukraine and conducted outreach on how to report suspected violations.
Angarella noted that since the beginning of the relevant activities, the USAID Office of Inspector General has received 178 reports of possible violations related to Ukraine, "which is 556% more than in the previous eleven months."
"To date, we have not had any serious criminal findings related to U.S. assistance to Ukraine. However, this increase in the number of reports shows that our outreach is working. And that people know how and to whom to report potential misuse of USAID funds," Angarella emphasized.
The acting USAID inspector general later said that her office is currently conducting two open investigations into possible misuse of U.S. aid and five more are under preliminary investigation.
She spoke about a case of potential abuse of tender procedures reported by "one of the large American contractors operating in Ukraine," but in this case, the case did not go to a prosecution, as it was warned.
"Serious conclusions will be drawn after a thorough investigation or audit process...so we have not confirmed any allegations to date," Angarella emphasized.
At a press briefing in Washington, D.C., National Security Council Coordinator John Kirby also said that the White House has no evidence that Ukraine has misused U.S. military aid.
"When it comes to the use of military assistance provided to Ukraine, we have not seen any evidence of any egregious violations," he said.
In particular, the coordinator emphasized that the Ukrainian side "shares our concerns about ensuring proper accountability and transparency with respect to equipment that is sent to or transported around the battlefield."
"Of course, we all want as much oversight and accountability as possible. Ukraine receives equipment and systems purchased with taxpayer funds, but this is a war. Real people are fighting and dying. During a battle, it is impossible to perfectly predict the movement of each unit that each individual soldier takes with him into battle," John Kirby said.
