you didn't do that...if you had shown any honest Critical Thinking, you'd have found the linked article which contains a great deal of information on this topic, as the following explains...

Q4: What are the oversight mechanisms for U.S. assistance?
A4: To date, Congress has appropriated a total of $42 million to support oversight of U.S. assistance to Ukraine for the Government Accountability Office (GAO), and the Offices of the Inspectors General (OIG) for the Departments of State, Defense and USAID. The three OIGs have collaborated closely, issuing a Joint Strategic Oversight Plan for FY 2023 outlining their planned workstreams for the fiscal year. Oversight efforts could be improved should the Department of State increase the cap on U.S. government personnel authorized to be in country and dedicate additional slots to the OIGs.
Legislation has been introduced in both the House and the Senate to establish a Special Inspector General for Ukraine, similar to those set up for Iraq and Afghanistan. This approach attempts to create a parallel that has little basis in reality. For example, after decades of war in Afghanistan, the interim government that assumed power in 2001 lacked the capacity to manage the immense amounts of aid—over $146 billion in 10 years. Additionally, decades of war and severe repression under the Taliban resulted in a stunted civil society sector that lacked the capacity to provide external transparency and accountability. Further, some have suggested that the Special Inspectors General in Iraq and Afghanistan provided a chilling effect on U.S. assistance efforts, reducing the appetite to take smart risks.
This is not the case in Ukraine where civil society and the government have demonstrated that they have the capacity to provide a level of accountability and transparency in fighting corruption. While Ukraine, undoubtedly, still has significant problems with corruption, both the government and business sector have shown signs of being serious about pushing institutional reforms to combat corruption. Since the 2014 Maidan Revolution, Ukraine has implemented a string of reforms aimed at combating corruption. According to the head of the National Anti-Corruption Bureau of Ukraine, together with the Specialized Anti-Corruption Prosecutors Office, nearly 300 investigations have been launched and a record 58 indictments have been sent to court in the last year. This includes a recent investigation implicating the first deputy minister for agrarian policy and a former deputy minister of economy involved in a corruption scandal around the procurement of food aid.
President Zelensky has personally taken steps to crackdown on corruption—firing regional military recruitment officials due to allegation of corruption. This progress was validated when in March 2023 the European Council’s Group of States against Corruption removed Ukraine from the list of countries deemed “globally unsatisfactory" due to endemic corruption. Additionally, civil society organizations banded together to tackle the challenges of endemic corruption. Following the full-scale Russian invasion, the RISE Coalition was launched to bring “integrity, sustainability and efficiency” to Ukraine’s recovery and reconstruction. The coalition now boasts 40 Ukrainian and international members.
Given both the difference in scale of assistance combined with the established anti-corruption mechanisms in Ukraine, instead of establishing a Special inspector General, Congress could establish a Lead OIG model, where one of the three inspectors general would serve as the Lead in order to streamline coordination and cooperation among the three OIGs with primary responsibility for oversight of aid—in this case USAID, the Department of Defense, and the State Department.

You also failed to look at the "Sources" in my original link...which included the U.S. Dept. of Defense, as well as a very reputable organization...'The Keil Institute'...and to make things even worse, you didn't take the time in your own Wiki link to note some of the members of the CFR...notably, Adm Bill McRaven (of 'Get bin Laden' fame), Janet Napolitano (HHS Sec'y), and Fareed Zakaria, noted foreign affairs expert.
While you went beyond what's typical in the way of research by many on this board, it wasn't enough, and was limited to a single criticism w/o any effort to explore "oversight" provisions...you simply stuck with a preconceived opinion. Hopefully, you now have a better understanding of what's actually going on...btw, it really didn't take me much time to find this material...a fraction of what it takes to document on this post, so don't hesitate to do the same next time.
