Senator Chuck Grassley released an unclassified document showing alleged payments from the CEO of Ukrainian gas company Burisma, Mykola Zlochevsky, to President Joe Biden and his son Hunter.

The document reveals an interview the Bureau of Investigation (FBI) conducted with a "confidential human source," who detailed the various meetings and encounters the Bidens had with a senior executive of Ukrainian natural gas company Burisma Holdings over several years beginning in 2015.

The FBI document also includes allegations that the Ukrainian company was forced to pay millions of dollars to the Bidens. In the document, Zlochevksy tells the source that he has many messages and recordings to show that he was pressured to pay that money.

Grassley claimed that the FBI tried to cover up the case. In addition, the Republican said that he has been following the case for a year. "NOW American people can see what I saw for the year I've worked to expose FBI document alleging criminal bribe between Biden and foreign national today."

He questioned the FBI's work. "What did the FBI do to investigate serious claims from FBIs own trusted source?" asked Grassley.

This Wednesday, the Iowa senator explained that in the FD-1023 file detailing the interview the FBI had with a highly credible source, they mention that the Ukrainian company executive decided to secretly record and keep the conversations he had with the then vice-president and his son as an "insurance policy."

According to the details Grassley provided, there are 17 recordings dating back to 2015, of which 15 were phone calls between the Ukrainian company and Hunter Biden, and the other two were with Joe Biden.
