From the transcript (the parts released to the public):
Zelenskyy: We are ready to continue to cooperate for the next steps specifically we are almost ready to buy more Javelins from the United States for defense purposes.
The President: I would like you to do us a favor though because our country has been through a lot and Ukraine knows a lot about it. I would like you to find out what happened with this whole situation with Ukraine, they say Crowdstrike... I guess you have one of your wealthy people... The server, they say Ukraine has it. There are a lot of things that went on, the whole situation. I think you're surrounding yourself with some of the same people. I would like to have the Attorney General call you or your people and I would like you to get to the bottom of it. As you saw yesterday, that whole nonsense ended with a very poor performance by a man named Robert Mueller, an incompetent performance, but they say a lot of it started with Ukraine. Whatever you can do, it's very important that you do it, if that's possible.
President Zelenskyy: Yes it is very important for me and everything that you just mentioned earlier. For me as a President, is very important and we are open for any future cooperation. We are ready to open a new page on cooperation in relations between the United States and Ukraine. For that purpose, I just recalled our ambassador from United States and he will be replaced by a very competent and very experienced ambassador who will work hard on making sure that our two nations are getting closer. I would also like and hope to see him having your trust and your confidence and have personal relations with you so we can cooperate even more. I will personally tell you that one of my assistants spoke with Mr. Giuliani just recently and we are hoping very much that Mr. Giuliani will be able to travel to Ukraine and we will meet once he comes to Ukraine. I just wanted to assure you once again that you have nobody but friends around us. I will make sure that I surround myself with the best and most experienced people. I also wanted to tell you that we are friends. We are great friends and you Mr. President have friends in our country so we can continue our strategic partnership. I also plan to surround myself with great people and in addition to that investigation, I guarantee as the President of Ukraine that all the investigations will be done openly and candidly. That I can assure you.
Now only a complete fool believes that you have to say "i want a quid pro quo" or " no investigation, no weapons" in order to be accused of criminal coercion, especially when this happened:
https://news.yahoo.com/military-ammunition-sale-to-ukraine-faces-near-yearlong-delay-000127481.html Zelenskyy bends over backwards to kiss Trump's butt to assure complete cooperation in his dig on the Bidens, Clinton and the 2016 election. Why? Because he needs those missiles as insurance against a Russian invasion.
Coincidence? Yeah, right!
