WASHINGTON — Two IRS whistleblowers who testified publicly about investigations into Hunter Biden's taxes have been promoted to new roles as senior advisers at the Treasury Department.

They helped bring about the downfall of Hunter Biden. Now, they're moving up in President Donald Trump's administration. Two IRS agents who blew the whistle on the agency's kid-gloves treatment of the former first son are being rewarded with top positions at the Treasury Department.

IRS whistleblowers Gary Shapley and Joe Ziegler, who squashed Hunter Biden’s sweetheart deal on his tax crimes — and then were kicked off the case and ostracized — have been promoted to leadership positions at the Treasury Department.
