Just days after being promoted to acting IRS commissioner, the whistleblower who testified publicly about investigations into Hunter Biden’s taxes is out again, according to three people familiar with the decision.

Gary Shapley — who became famous after speaking out about alleged political influence in the Hunter Biden tax probe — is out as IRS director after just two days, following an internal struggle involving Elon Musk.

Gary Shapley, whom President Donald Trump named acting commissioner of the Internal Revenue Service earlier this week, will no longer serve in the role, according to a White House official and a source briefed on the matter.
