Republican Senator Chuck Grassley has revealed that a Ukrainian businessman claimed to have 15 audio recordings of Hunter Biden and two of Joe Biden, allegedly kept as "insurance" in relation to a bribery scheme involving Burisma Holdings owner Mykola Zlochevsky. Grassley accused the FBI of redacting information about the recordings from a file shared with House lawmakers and questioned what the Justice Department had done to investigate the matter.

The bribery allegation against Biden was first made in 2017, but the informant file read by House lawmakers last week was created by the FBI in June 2020 after that tip received fresh attention.
