The IRS whistleblower is a supervisory criminal investigative agent who led the team probing Hunter Biden's potential tax crimes – until, as that letter reveals, he and his entire team were suddenly REMOVED from the case by order of Merrick Garland, the head of Biden's Department of Justice.

He had received whistleblower protection a few weeks ago from Congress and the Justice Department inspector general as he sought to disclose evidence that showed Garland the DOJ were not treating the case fair and instead were trying to interference in the probe against the president's son.

Attorneys for the whistleblower say this is MOST CERTIANLY an act of RETALIATION on top of obstruction of Congressional inquiries.

"Today the Internal Revenue Service (IRS) Criminal Supervisory Special Agent we represent was informed that he and his entire investigative team are being removed from the ongoing and sensitive investigation of the high-profile, controversial subject about which our client sought to make whistleblower disclosures to Congress," the whistleblower's lawyers, Mark Lytle and Tristan Leavitt, wrote in a letter to multiple House and Senate committees.

"He was informed the change was at the request of the Department of Justice."
