Hunter Biden sued the U.S. Internal Revenue Service alleging that so-called IRS whistleblowers illegally disclosed information about his taxes.
President Joe Biden's son, who was indicted last week on firearms charges after a plea agreement with federal prosecutors collapsed, filed the suit Monday in federal court in Washington.
Under the deal, he had agreed to plead guilty not only to charges that he purchased a firearm without disclosing that he was unlawfully using drugs, but also to two misdemeanor tax crimes.
The lawsuit refers to an "assault" on his rights involving the public disclosure of his confidential tax information during televised interviews with IRS employees.
