A Treasury Department inspector general is probing efforts by President Donald Trump and Elon Musk’s Department of Government Efficiency to obtain private taxpayer data and other sensitive information, internal communications reviewed by ProPublica show.

The office of the Treasury Inspector General for Tax Administration has sought a wide swath of information from IRS employees. In particular, the office is seeking any requests for taxpayer data from the president, the Executive Office of the President, DOGE or the president’s Office of Management and Budget.

The request, spelled out in a mid-April email obtained by ProPublica, comes as watchdogs and leading Democrats question whether DOGE has overstepped its bounds in seeking information about taxpayers, public employees or federal agencies that is typically highly restricted.

The review appears to be in its early stages — one document describes staffers as “beginning preplanning” — but the email directs the IRS to turn over specific documents by Thursday, April 24. It’s not clear if that happened.
