what did he do? the only person other than the people that filed the memo was vindman. he was the only person on the phone call.
he admited that the memo was correct according to his notes. he also when asked couldn't point out any quid pro quo.
he had some disagreements over policy but that is not illegal.
no one else that testified has any knowledge of the phone call or what was said.
they are simply spouting off 3rd and 4th sources of information which is hearsay and not reliable.
so there was no abuse of power.
if you think it is abuse of power to withhold funding until a government gets a hand on corruption then
every president that has ever been elected has abused their power.
presidents have abused the power for the past 2 centuries.
For starters, the fact you are of the mindset that the single phone call with Zelensky is what this is all about is likely a root cause of your confusion here. There is much, much more to this abuse of power scheme than a single phone call. This scheme began months before the phone call that culminated in Trump's continuance of corrupt actions.
Donald Trump engaged in a wide-ranging abuse of power scheme. He attempted to extort Ukraine into publicly announcing the opening of a corruption investigation into his chief political opponent in the upcoming election. A public announcement that would include key words and phrases in which were approved by him. He wanted President Zelensky to personally deliver the remarks publicly on either CNN or Fox. Even suggesting somewhere like on Tucker Carlson as an acceptable outlet. This was to be done to further his electoral chances in 2020. He did not care about general corruption, or even if there was corruption engaged in by the Bidens. He wanted a public announcement so that he could beat his opponent over the head with it for months and months, the same way he was successfully able to do to Clinton.
In exchange for this public announcement, he was willing to withhold military aid and an official State Visit, both of which were desperately sought by the Ukrainians. The prior was also very much in our national security interests. So Trump was willing to damage our national security in exchange for receiving something of value that would personally benefit him. Not only is this very much not okay and completely wrong, but it is exactly what is defined as being a High Crime. That makes it very much impeachable.
If not for the whistle-blower coming forward and warning of this extreme abuse of power scheme transpiring, we may have never known about this. But the WB filed a report, that was then corroborated by the Trump-appointed IC IG as being both urgent and credible. It was not until this point in time that the Trump administration realized just how screwed they were, and they then opted to release the aid to Ukraine, even without the public announcement being made. However, the cover-up had been in full swing at this point. Following the call that directly implicates Trump in seeking the quid-pro-quo with Zelensky (remember, he did not mention the word 'corruption' one single time on the call) his top administration lackeys scrambled to hide the call on a code-level server that could only be accessed by a select few. But it did not matter by then, because all of the back-channel shenanigans had left a long paper trail of the abuse of power scheme. These are corrupt people, led by the most corrupt of them all in Trump. But they are not geniuses. They are a bunch of morons that felt they were above the rule of law, above the Constitution, and would be capable of doing whatever they needed to do in order to retain power for themselves.
You may not like it. You may even pretend this is not real. But you would be wrong. This is all truth my friend. Trump abused the power granted to him by the people, trying to impact the outcome of the election in his favor, through the use of extortion and foreign interference. THIS. IS. WRONG!
