You have the transcript go ahead use them I did
The transcript is not a legal document. The participants were not under oath and neither were the transcribers. Also, the transcript raises many questions that only Trump and his senior staff can answer.
You may love Trump and don't want to have his presidency cut short, I get that, but if he can refuse to be investigated/testify, expect the next president, whom you may not like so much, to do the same. What we'll have are imperial presidents with little or no checks on their power. How many times did Hillary testify in front or Congress? In the future such testimony will never occur.
