So, the first conversation is dated November 16, 2016.

In it, Biden talks about the difficulties of transferring cases across Ukraine to the new administration in the White House.

From the conversations it follows that Poroshenko asked Biden to support the topic of visa-free travel with the EU, which could be “sold” to the Ukrainian people.

In one of the entries, Biden called Poroshenko the father of the nation, and compared the current American leader Donald Trump with a dog that runs after a car along the road, then grabs it, but does not understand what to do with it.

In May, Derkach first published recordings of telephone conversations with voices similar to Poroshenko and Biden.

As the deputy said, they testify "to the facts of international corruption and treason at the highest state level."

Poroshenko called the records fabricated.
