IRS Whistleblower Says U.S. Is Mishandling Hunter Biden Probe

WASHINGTON—An IRS supervisor has told lawmakers he has information that suggests the Biden administration is improperly handling the criminal investigation into President Biden’s son, Hunter Biden, and is seeking whistleblower protections, according to people familiar with the matter.  

A letter sent to Congress on Tuesday says a career Internal Revenue Service criminal supervisory special agent has information that would contradict sworn testimony by a “senior political appointee.” The supervisor also has information about a “failure to mitigate clear conflicts of interest in the ultimate disposition of the case,” according to the letter.
