It seems obvious that there was more than one instance were trump introduced the idea of quid pro quo---but I have argued that in another thread so please follow that one.
Keep in mind that the "complete transcript" that trump promised was no such thing. The time it takes to read the entire transcript (of notes) at a conversational speed is just over 10 minutes. The entire call is said to have lasted about 30 minutes. So---what happened in the "lost" time---heavy breathing
Just for the record---I am not prejudiced (defined as: preconceived opinion that is not based on reason or actual experience.) against trump. Rather my dislike and distrust of trump is based on factual experience over a long period of time.
As for defending Biden--I'll pass that to someone who might be vested in that argument---I'm not.
