Update: The US Government has found no significant cases of waste, fraud, or abuse related to Ukraine aid
The DoD, State Department, and USAID OIG compiled an extensive report covering 113 Billion dollars in American support to Ukraine since the February, 2022 full scale invasion.
On March 27, 2023, a joint oversight report was released which looked into US aid to Ukraine after the full-scale invasion by Russia. The entire document can be found here and below is an official one-page summary.
Not that anyone doubted it, I suppose this is in response to the toxic milbloggers from Mordor [does that sound like a punk rock band to you?] saying that it was all being squirrelled away into the personal accounts of the bigwigs of Ukraine?
Unfortunate the fox news, tea party confederates in Congress still won't believe it
