The recording of a call from then Vice President Joe Biden to Ukrainian President Petro Poroshenko, after it was known in 2016 that the new president would be Donald Trump, shows that Biden risked national security and tried to sabotage Trump.

While still in office, Biden not only spoke ill of the incoming administration but tried to channel information from the state to him as he moved into the role of an ordinary citizen, according to The Federalist on Sept. 17.

“The truth of the matter is that the incoming administration doesn’t know a great deal about [Ukraine],” Biden told Poroshenko, insisting that Trump’s team was not prepared for the transition of command, a claim that undermined its effectiveness in the face of a foreign power.

Biden also claimed that he would continue to influence foreign policy even after he was replaced by the new vice president.

“I don’t plan on going away. As a private citizen, I plan on staying deeply engaged in the endeavor that you have begun and we have begun,” Biden reiterated to Poroshenko, and this attempt to remain on official business that no longer pertains to him could be a violation of the Logan Act.

Even more compromising is the situation for Biden because he knew that the Obama administration planned to investigate the campaign of president-elect Donald Trump, blaming him for collusion with Russia.

This costly investigation promoted by the Democrats found no evidence against Trump.

Biden’s call to Poroshenko is not the only one that involves him in controversial activities with the Ukrainian president.

In another leaked audio, Biden told Poroshenko that Ukraine would receive U.S. assistance when former Prosecutor General of Ukraine Viktor Shokin, who was investigating the energy company Burisma Holdings where Biden’s son Hunter Biden was replaced, was arrested.

This conversation was referred to by the Ukrainian president who succeeded Poroshenko, Volodymyr Zelenskiy, who said it “could be perceived and qualified as high treason.” The recordings were released by Andriy Derkach, a member of the Ukrainian Parliament, according to The Washington Post on May 20.

“And I’m a man of my word. And now that the new prosecutor general is in place, we’re ready to move forward to signing that new $1 billion loan guarantee. And I don’t know how you want to go about that. … I’ll leave it to you to how you want it done and where you want it done,” the man identified as Biden added in the conversation.
