He just nuked all the Republicans talking points
"I followed the directions of the President," said Sondland.
"Everyone was in the loop. It was no secret. Everyone was informed via email on July 19, days before the Presidential call. As I communicated to the team, I told President Zelensky in advance that assurances to 'run a fully transparent investigation' and 'turn over every stone' were necessary in his call with President Trump."
"I know that members of this Committee have frequently framed these complicated issues in the form of a simple question: Was there a 'quid pro quo?' As I testified previously, with regard to the requested White House call and White House meeting, the answer is yes."
and he has emails to prove what he is saying
"Within my State Department emails, there is a July 19 email that I sent to Secretary Pompeo, Secretary Perry, Brian McCormack (Perry's Chief of Staff), Ms. Kenna, Acting Chief of Staff and OMB Director Mick Mulvaney (White House), and Mr. Mulvaney's Senior Advisor Robert Blair. A lot of senior officials.
Here is my exact quote from that email:
"'I Talked to Zelensky just now... He is prepared to receive Potus' call. Will assure him that he intends to run a fully transparent investigation and will 'turn over every stone'. He would greatly appreciate a call prior to Sunday so that he can put out some media about a 'friendly and productive call' (no details) prior to Ukraine election on Sunday." Chief of Staff Mick Mulvaney responded: 'I asked NSC to set it up for tomorrow.'"
