Since when is a quid pro quo illegal or even wrong? Life is full of quid pro quos. If I ask you to kill someone for me and offer you money for doing so, that is a quid pro quo and is illegal and wrong. If I give you a dollar for a candy bar, that is a perfectly good quid pro quo. Foreign policy decisions are nothing but a quid pro quo. This administration had concerns that Ukraine was corrupt and would not cooperate with AG Barr and his investigation into the 2016 election including Crowdstrike. They could have made the loan guarantees subject to conditions around that investigation and there would be nothing wrong with doing so. They didn't even bother to do that.
Those of you idiots trying to make something more of that phone call just highlight the fact that you have nothing other than trumped up accusations.
