According to Sondland, he specifically told Ukraine he'd speak to Trump about the issue with the security assistance. I'd like to know what that conversation entailed.
"September 1 – Warsaw Meeting There was a September 1 meeting with President Zelensky in Warsaw. Unfortunately President Trump’s attendance at the Warsaw meeting was cancelled due to Hurrican Dorian. Vice President Pence attended instead. I mentioned to Vice President Pence before the meetings with the Ukrainians that I had concerns that the delay in aid had become tied to the issue of investigations. I recall mentioning that before the Zelensky meeting. During the actual meeting, President Zelensky raised the issue of security assistance directly with Vice President Pence. The Vice President said he would speak to President Trump about it. Based on my communications with Secretary Pompeo, I felt comfortable sharing my concerns with Mr. Yermak. In a very brief pull-aside conversation, that happened within a few seconds, I told Mr. Yermak that I believed that the resumption of U.S. aid would likely not occur until Ukraine took some kind of action on the public statement that we had been discussing for many weeks."
