Delaware Attorney David Weiss, who has served since the Donald Trump administration, will have to make the final decision on whether to bring charges.
The investigation began back in 2018 and caught Trump's attention during the 2020 presidential election.
In June, the Russian Ministry of Defense reported that documents from entities reporting to Hunter Biden and involved in military biological projects in Ukraine may indicate the concealment of profits and tax evasion.
In November 2019, the lawyer of former US President Donald Trump, Rudy Giuliani, said that he had compromising evidence on the Joe Biden family.
According to him, this refers to "documents about the Biden family, telling about four decades of their making money in the office."
According to Hunter Biden, he was not engaged in illegal activities in Ukraine, where he was a member of the board of the oil and gas company Burisma.
At the same time, Trump claimed that Joe Biden's son received money from Ukraine and China.
However, in March 2022, the Daily Mail revealed evidence of Hunter Biden's involvement in the activities of biolaboratories in Ukraine.
