Re: Ukraine quid-pro-quo seems to have happened under Obama
> Yes, Trump phrased it as "I would like you to do us a favour", but both sides knew what he meant.
Opinion, not fact. Also, the "do us a favor" comment was in regard to investigating Ukrainian corruption in the 2016 election - not in regard to Joe Biden.
> 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?
There is no evidence that Trump demanded anything. In fact, all the actual evidence shows that Trump made no demands, or deals. Not one witness has claimed that Trump ever said anything like: "get me dirt on Biden, or I will cancel US aid."
Also, if there is evidence of corruption - which there clearly is - I think the president would be remiss in his/her duties to not investigate.
And Trump did *not* make the investigation public - the democrats did that. Had the so-called "whistleblower" report never been made public, the public would not know anything about Biden being "investigated." Although, I am not sure Trump asking Zelensky to look into Biden is a formal investigation.
> 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.
Trump did *not* press another country to persecute US citizens. Trump asked for information because - even according to the left - there is evidence of corruption. Again, Trump would be completely remiss in his duties to turn a blind eye to corruption at the highest level.
