Ron Johnson suggests Democrats tampered with the Epstein files: "I do know that the Epstein files were in the custody of the Biden administration. I don't know to what extent they added or deleted things."

The claim consists of two parts: first, that the Epstein files were in the custody of the Biden administration, and second, that there may have been additions or deletions made to those files by Democrats. The first part about custody is plausible given that federal investigative files typically transfer between administrations; however, there is no public documentation confirming the specific handling or control of Epstein-related files by the Biden administration.

The second part, implying tampering (adding or deleting information), is a serious allegation requiring strong evidence. No credible sources or official investigations have substantiated claims of deliberate alteration of these files by Democrats or any administration officials. The search results do not provide any direct evidence supporting this claim, and the cited Newsweek article does not address this allegation.

Without verifiable proof, this remains an unsubstantiated assertion. Given the lack of evidence and the serious nature of the claim, it cannot be confirmed or denied based on available information.
