PJ Media has a good article about this. FTA:
On Thursday, the Government Accountability Office (GAO) ruled that Trump violated the law by temporarily withholding aid to Ukraine. But, if the Trump administration broke the law, then Joe Biden (and the Obama administration) broke the law, too…
Biden argued that his actions were above board because he was carrying out the “official policy” of the Obama administration to root out corruption in Ukraine. “It was a fully transparent policy carried out in front of the whole world and fully, fully embraced by the international community of democracies,” he claimed.
Here’s the problem with that defense: like the military aid at issue with Trump and Ukraine, the $1 billion loan to Ukraine was also appropriated by Congress. The loan was part of a bill that was passed in March 2014, with a 399 to 19 vote in the House and a 98 to 2 vote in the Senate. By the GAO’s own reasoning with regard to the aid withheld by the Trump administration, the withholding of aid by Biden on behalf of the Obama administrations also broke the law.
