Former Ukrainian Prosecutor General Viktor Shokin has claimed that Joe Biden, while serving as US vice president, received a bribe from a Ukrainian energy company in exchange for helping to get him fired in 2016.  

In an interview with Fox News released on Friday, Shokin said that Biden pressured then-Ukrainian President Pyotr Poroshenko to fire him over his investigation into Burisma Holdings, a Ukrainian energy company on whose board Hunter Biden, the incumbent US president's son, served at the time.   

The ex-prosecutor argued that both Poroshenko and Joe Biden understood that if he had been allowed to continue his probe into Burisma, it could have provided "the facts about the corrupt activities" by Hunter Biden, Devon Archer – the company's another American executive – and other people involved.  

However, Poroshenko offered a different version of events, insisting that Shokin was fired because of his failure to fight corruption in Ukraine.
