Struggle Over Americans’ Personal Data Plays Out Across the Government

Employees from Elon Musk’s so-called Department of Government Efficiency are gaining access to vast amounts of information held by federal agencies, even as lawsuits try to stop them.

Last week, Michelle King, the acting commissioner of the Social Security Administration, sought to reassure Democrats on Capitol Hill about the presence of two of Elon Musk’s allies at her agency.

The Social Security Administration keeps medical information, bank account numbers and other sensitive personal data about the roughly 70 million Americans it provides with more than $1 trillion in benefits annually. In the Feb. 11 letter to Senator Ron Wyden, Democrat of Oregon, Ms. King said that the two representatives, from the so-called Department of Government Efficiency, or DOGE, had not yet seen personal information — and said any disclosures would follow established procedures.

“I share your commitment to protecting sensitive personal and financial information from improper disclosure and misuse,” she wrote in the letter, which was viewed by The New York Times. “We follow all relevant laws and regulations when granting access to S.S.A. systems.”

Days later, Mr. Musk’s team sought access to the agency’s data. Ms. King resisted the request, and by Monday night she and her chief of staff, Tiffany Flick, were out of their jobs, according to three people familiar with their departures. The Trump administration elevated Leland Dudek, a relatively low-level staff member who had previously collaborated with DOGE, to temporarily lead the agency.

The episode at the Social Security Administration, which did not respond to requests for comment, has played out repeatedly across the federal government. In its stated quest to root out fraudulent government spending, Mr. Musk’s team of software engineers has repeatedly sought unfettered access to the wide range of personal information the U.S. government collects about its residents. The requests have often alarmed career civil servants used to jealously guarding data whose improper disclosure can in some cases violate federal law.

At the Internal Revenue Service, Mr. Musk’s team is seeking to give at least one of its members, a software engineer named Gavin Kliger, broad access to the data included in the roughly 270 million tax returns that American individuals, businesses and nonprofits file each year.
