A lawsuit filed Monday seeks to halt the ‘unlawful disclosure of information,’ including Treasury data on Americans’ taxes and Social Security, to DOGE staff. This week, President Trump adviser Elon Musk’s newly formed Department of Government Efficiency (DOGE) seems to have gained full access to the Department of Treasury’s payments systems responsible for processing trillions of dollars of spending,

Democratic lawmakers have expressed concern that access to the system could allow DOGE, which disburses nearly 90% of all federal payments, to restrict disbursement of federal funds.

A senior U.S. lawmaker says representatives of Elon Musk were granted “full access” to a U.S. Treasury payments system used to disperse trillions of dollars to Americans each year and warned that Musk’s access to the system poses a “national security risk.”
