This post, which notably is only a Bluesky post that includes no sources, is MISLEADING IN ITS FIRST CLAIM AND FALSE IN ITS SECOND AND THIRD.
Breaking this post down into two parts, let's start with the claim about Joe Biden withholding a loan guarantee from the Ukrainian government. The way this claim is worded, it is true but extremely misleading. According to multiple sources, such as this USA Today article and this Reuters article, as Vice President, Biden withheld a $1 billion USAID loan guarantee unless Ukraine fired the prosecutor Viktor Shokin. Shokin was looking into Burisma Holdings Ltd., a Ukrainian natural gas company who had Hunter Biden, the Vice President's son, on their board; however, this is not the reason Biden wanted Shokin ousted. In fact, Shokin was seen as inadequate in his role as prosector by many. "'[Joe Biden] was acting alongside our European allies. Everybody was of a single mind that this prosecutor was not the right guy for the job'" said Charlie Kupchan in that same USA Today article. Although the fact that his son was on Burisma's board might have undermined some of his anti-corruption messaging in Ukraine, as discussed in this New York Times article, Biden withheld the aid until Shokin was voted out in March 2016 only because Shokin was seen as not pursuing corruption in the Ukrainian government as was deemed necessary.
As for the second part of the post, this EUvsDisinfo page refutes these two claims and explains the situation very well. It links direct sources such as this research report while outlining how the Russian government made a popular protest in Ukraine look like a coup d'état supported by the U.S. government.
