Ukrainian officials say they were offered $6 million in bribes to end a criminal investigation into the head of a gas company where the son of former U.S. Vice President Joe Biden served on the board.
Ukraine's anti-corruption prosecutor, Nazar Kholodnitskiy, told a press conference in Kyiv on June 13 that neither of the Bidens was connected to the alleged bribe attempt.
The Burisma natural gas company was at the center of a scandal leading to U.S. President Donald Trump's impeachment trial.
Biden is Trump’s Democratic challenger in the November presidential election.
"The total confiscated was $6 million. This a record amount for a bribe in Ukraine, as far as I remember," said Artem Sytnyk, the head of the National Anti-Corruption Bureau, during the news conference.
Kholodnitskiy and Sytnyk said the bribe was intended to encourage their offices to drop a probe into Mykola Zlochevskiy, the head of Burisma and a former minister of ecology.
Zlochevskiy is suspected of using his ministerial position for personal gain.
In a statement, Burisma said the company had nothing to do with the bribe attempt.
During a July 25 phone call, Trump urged his Ukrainian counterpart, Volodymyr Zelenskiy, to investigate Biden and his son, Hunter Biden, according to a transcript of the conversation.
Critics said the Trump administration withheld crucial military aid worth $391 million to Kyiv as leverage.
In January, Democrats in the House of Representatives charged Trump with abuse of office and obstruction of Congress, allegations he rejected as a political "witch-hunt."
The president was acquitted following a trial in the Senate in a vote mainly along party lines.
