Prosecutors in Hunter Biden’s upcoming federal tax trial in California intend to present evidence showing that the first son received payments from a foreign client in exchange for influencing U.S. policy.

The evidence supports a major claim made by IRS whistleblowers to Congress last year. According to Just the News, the Department of Justice had evidence of Hunter Biden’s alleged crimes but failed to bring charges before the statute of limitations ran out.

Motions filed earlier this week reveal that federal prosecutors plan to present evidence at trial to show that Hunter Biden and his business associates were paid by a Romanian businessman to influence U.S. policy and public opinion.

Tristan Leavitt, president of Empower Oversight and representative for IRS whistleblower Gary Shapley, described the new filing as “infuriating” in a post on X Thursday.

“…Special Counsel Weiss is demonstrating to a T exactly what SSA Shapley and SA Ziegler blew the whistle on: Weiss’s office had clear evidence of crimes by Hunter Biden that they almost swept under the rug when they allowed the statute of limitations to expire,” he wrote. “Weiss is just using the Romanian payments as evidence of intent to evade taxes But the evidence (not ‘allegations,’ as the filings point out) shows what Hunter Biden ‘did do for [Gabriel Popoviciu]’–and the fact of the matter is that it violated the Foreign Agents Registration Act,” he added.

The possibility of violations of the Foreign Agents Registration Act (FARA) has hovered over Hunter Biden’s business dealings, with Shapley testifying that his team was impeded from further investigation.

House Republican committees leading the impeachment inquiry into President Biden have identified this pattern in multiple deals, not just the Romanian arrangement detailed in the court filing.

They accuse Hunter Biden of engaging in an “influence peddling” scheme with various foreign clients. However, the impeachment effort has lost momentum since President Biden announced that he will not seek reelection.
