A previously anonymous IRS whistleblower alleging political interference in the Hunter Biden probe revealed his identity as special agent Joseph Ziegler at a House Oversight Committee hearing on July 19.

Mr. Ziegler appeared publicly for the first time at the hearing, describing himself as a gay Democrat who has worked in the IRS Criminal Investigation Division for 13 years. He and IRS Supervisory Special Agent James Shapley had given closed-door testimony to another House panel alleging misconduct in the federal probe of Mr. Biden’s tax matters, and he was previously identified only as “Whistleblower X.”
