> 2. It is unprecedented for a president to demand the investigation of any US citizen in a phone call to a foreign head of state (let alone a highly political investigation).
Trump did not "demand" anything. Read the transcript. Also, is it really unprecedented for a president to demand the investigation of any US citizen? My understanding is that the president is in charge of federal law enforcement. And yet, in all of US history the president has not had a US citizen investigated?
I have read and reread the call summary (it is not a "transcript" as the document itself makes clear).
There is testimony from multiple witnesses that it was clear going into the meeting that Zelensky had to publicly announce investigations if he wanted the previously promised White House visit. Yes, Trump phrased it as "I would like you to do us a favour", but both sides knew what he meant. Overtly tying military aid to the investigations came later, but Trump was pressing for investigations, and not willing to do this through normal channels.
If you consider this normal, identify for me one other example of a US president directly asking a leader of a foreign country to investigate a US citizen. Why did Trump demand that the investigations be announced publicly rather than (as is normal in criminal investigations) it be done quietly until there are indictments to announce?
[I do not know why I am bothering to point out the absurdity of claiming it is normal for a US president to press another country to persecute US citizens. You clearly either cannot think straight or, as I believe, are just a stinking troll.]
