Remember, BOLTON isn't the only witness who can testify to a quid pro quo. GIULIANI can confirm it. And PARNAS. And FRUMAN. And PERRY. And NUNES. And HARVEY. And POMPEO. And DIGENOVA. And TOENSING. And MULVANEY. SONDLAND told VOLKER and TAYLOR he was aiding a TRUMP quid pro quo. 
PS/ Don't fall into the trap of believing BOLTON and TRUMP are in a "he said, he said" situation—though of course even if they were, you always believe the person in that situation who's willing to testify under oath (BOLTON). More than a dozen witnesses would corroborate BOLTON.
PS2/ Indeed, as a longtime trial lawyer I'd like to make a clarification: it's not even a "he said, he said" situation...
...until *both parties testify under oath*! So TRUMP hasn't even *earned* the "he said, he said" designation, because he's refused to testify. BOLTON hasn't.
