What is causing alarm at the IRS regarding Elon Musk's DOGE team?

The IRS is alarmed about a request from Elon Musk's DOGE team to access sensitive taxpayer information and financial data. The situation has created significant concern within the agency, with political pressure reportedly coming from the White House. This controversy coincides with the sudden resignation of the Social Security Administration's acting head following what was described as a clash with Musk's team over access to sensitive data in that system. As reported by the Washington Post, a memorandum of understanding between the White House and the IRS has not yet been codified, meaning the DOGE team has not yet gained access to the sensitive IRS systems.
