Some of the savings touted by Elon Musk’s Department of Government Efficiency are incorrect or lack supporting evidence, according to federal auditors.

DOGE began posting its estimated savings on a web page known as the Wall of Receipts. Lawmakers asked the Government Accountability Office to evaluate the accuracy of the estimates, and the watchdog found them lacking in some cases.

Auditors found that 108 of 264 leases identified for termination on the Wall of Receipts were already in the process of termination when DOGE was established. In another case, DOGE reported $1.7 billion in savings on a Department of Defense contract for IT services, but in the end, no action was taken to terminate the contract, so no savings were achieved.

More broadly, DOGE was not transparent regarding the methodologies used to calculate savings. The GAO said DOGE officials did not respond to requests for information. The report concluded by saying the data quality issues found limit the value of the Wall of Receipts for policymakers.

“In addition, when government data are not reliable, it can hinder the public’s trust in government,” the report stated.
