Here is my view:
1: (False) The phone call was not perfect, it was full of quid pro quo
2: (False) The phone call recording should provide ample evidence alongside testimonies from those directly affected and involved
3: (False) If he did it, it definitely is an impeachable issue
Try considering just the evidence of the trial, not that it's Trump being investigated, or the democrats doing the investigation, and no 'us vs them' mentality.
True or False: 1- 'it was a perfect phone call, there was no quid pro quo'
True or False: 2 - 'it's all hearsay and second hand information' (this implies that direct evidence would be relevant)
True or False: 3 - 'if he did do it, it's not impeachable'
