President Donald Trump asked Ukraine President Volodymyr Zelensky to do us a favor, though immediately after Zelensky told Trump he was grateful for the military aid the U.S. provided to his country, according to a White House summary of a July 25 phone call between the two leaders.

That request and Trumps implied threat that U.S. military aid to Ukraine was at stake if Zelensky did not comply has become central to Democrats push to impeach the president .

The favor Trump requested from Zelensky was twofold. First, Trump asked Ukraine to investigate a conspiracy theory that the Democratic National Committee servers Russia hacked in 2016 to aid Trumps campaign were not actually hacked by Russia. Moments later, Trump asked that Ukraine open an investigation into his potential 2020 rival, former Vice President Joe Biden, and Bidens son Hunter Biden. Trump also asked Zelensky to meet with Rudy Giuliani, the former New York City mayor who acts as Trumps private consigliere in Ukraine, and to speak by phone with Attorney General William Barr to discuss the investigation.

The connection between the Zelenskys mention of U.S. military aid and Trumps request for a favor is clear in the summary the White House released Wednesday. The summary is a collection of notes and recollections of Situation Room duty officers and National Security Council policy staff.

After congratulating Zelensky on his election victory, according to the summary, Trump pivoted to talking about how much aid the U.S. has given to Ukraine compared to other countries, Germany in particular. I wouldnt say that its reciprocal necessarily because things are happening that are not good but the United States has been very, very good to Ukraine, Trump notes, implying that Ukraine hasnt kept up its end of the bargain.

I would also like to thank you for your great support in the area of defense, Zelensky replied. We are ready to continue to cooperate for the next steps, specifically, we are almost ready to buy more Javelins [anti-tank missiles] from the United States for defense purposes.

It is here that Trump, after complaining that Ukraine has not reciprocated adequately in exchange for U.S. aid, linked Zelenskys mention of military aid to his own requests.

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, Trump said. The key word in this response is though it implies a link between Zelenskys praise for U.S. military aid to the coming request.

Trump first requested information from Zelensky related to the DNC server conspiracy theory. Then he pivoted to Biden.

The other thing, Trump said, theres a lot of talk about Bidens son, that Biden stopped the prosecution and a lot of people want to find out about that so whatever you can do with the attorney general would be great.

Trump went on, per the summary: Biden went around bragging that he stopped the prosecution so if you could look into it ... it sounds horrible to me.

Rep. Adam Schiff (D-Calif.), chairman of the House Intelligence Committee, said Wednesday that those notes reflect is a classic mafia-like shakedown of a foreign leader.

This is how a mafia boss talks, he added. What have you done for us? Weve done so much for you, but there isnt much reciprocity.

Several House committees have started investigating whether Trump also delayed more than $250 million in aid to Ukraine as he pressed Zelensky to look into Biden. The summary shows an implicit connection between the aid and the investigation in the conversation between the two leaders.

The president has provided wildly varying accounts of the call with Zelensky in the wake of a series of bombshell reports claiming he asked a foreign power to investigate the former vice president, one of his prime rivals in the 2020 election, and may be guilty of a criminal violation in doing so.

Given the Trump administrations history of editing documents, theres no guarantee that this release tells the full story of the phone call between the two world leaders.
