Why do I think a transcript released by Trump would be cooked up? 
Because you are reaching to reinforce your bias against him. I'm sure an audio version has been checked by somebody or again, a leaker would pop up.
Remember in 8 years of the "most transparent administration in history" there was not one leak, not one mention of anything and so much was done....endless bailouts, drone use on civilians, cash on pallets to Iran, a nuke deal with Iran that they never signed, on and on...
That's the reason Obama won't endorse ol' Joe....wants to leave those dogs lying where they are.
