Hunter Biden Sues I.R.S., Saying Disclosures by Agents Violated His Privacy

Hunter Biden sued the Internal Revenue Service on Monday, saying that investigators for the agency violated his privacy rights by disclosing details to Congress and the public about his taxes and the investigation into his conduct.

Mr. Biden, the president’s son, filed the suit days after the Justice Department indicted him on separate charges relating to his purchase of a handgun in 2018. The decision to go ahead with the suit shows that he and his legal team are continuing to take an aggressive stance in fending off inquiries from congressional Republicans even as he faces the possibility of further prosecution on tax charges by the Justice Department amid his father’s re-election campaign.
