A Ukrainian lawmaker has leaked the audio of a phone call between then-Vice President Joe Biden and former Ukraine President Petro Poroshenko which appears to confirm that a quid pro quo existed.

Biden can be heard in the recording saying, “I am prepared to do a public signing of the commitment for the billion dollars.”

Poroshenko responds that he asked the prosecutor in question, Viktor Shokin, to resign despite having no evidence of him “doing anything wrong.”

Biden replies, “I’m a man of my word. Now that the new prosecutor general’s in place, we’re ready to move forward in signing that new one billion dollar loan guarantee.”

Listen to the damning audio for yourself:

In footage from a 2016 panel hosted by the Council on Foreign Relations, Joe Biden appeared to brag about using his power as Vice President to get Shokin fired with the threat of withholding one billion dollars in U.S. loan guarantees from Ukraine.

Then-Vice President Biden can be heard saying,

“I said no, we’re not gonna give you the billion dollars. They said ‘you have no authority, you’re not the president, the president said–’ I said ‘call him’. I said ‘I’m telling you you’re not getting a billion dollars.’ I said ‘You’re not getting the billion– I’m gonna be leaving here in six hours. If the prosecutor’s not fired, you’re not getting the money.’ Well son of a bitch, he got fired. And they put in place someone who was solid.”

Making matters worse, some say Biden’s targeting of Ukrainian prosecutor Viktor Shokin was intended to disrupt a corruption investigation into the energy company Burisma for which Biden’s son Hunter Biden served as a board member.

As we reported last year, Hunter Biden appears to have greatly benefited financially from his position on the board of Burisma, or more likely from being his father’s son, as he was paid more than the rest of the board despite his lack of any relevant qualifications.
