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.

The department said that no payments would be interrupted and that it was conducting a review of the integrity of the system.

A Treasury Department official has written a letter to federal lawmakers saying that a tech executive working with Elon Musk’s “Department of Government Efficiency” will have “read-only access” to the government’s payment system.
