Ukraine is ready to investigate the connections Joe Biden’s son Hunter Biden had with the Ukrainian natural-gas company Burisma Holdings, according to Anton Geraschenko, a senior adviser to the country’s interior minister who would oversee such an inquiry.

Geraschenko told The Daily Beast in an exclusive interview that “as soon as there is an official request from the Trump administration, we’ll look into it,” but “currently there is no open investigation.”

“Clearly,” said Geraschenko, “Trump is now looking for kompromat to discredit his opponent Biden, to take revenge for his friend Paul Manafort, who is serving seven years in prison.” Among the counts on which Manafort was convicted: tax evasion. “We do not investigate Biden in Ukraine, since we have not received a single official request to do so,” said Geraschenko.
