A U.S. judge has temporarily blocked a government team created by former President Donald Trump from accessing sensitive information from the U.S. Education Department and the Office of Personnel Management.

The team, called the Department of Government Efficiency (DOGE), was led by billionaire Elon Musk.

Judge Deborah Boardman in Maryland issued the ruling after labor unions challenged the agency’s decision to grant DOGE access to private records. The unions argued that giving DOGE such access violated federal law, including the Privacy Act of 1974.

The judge agreed, stating that both agencies likely broke the law by allowing DOGE to view personal data.

The records in question include Social Security numbers, birth dates, home addresses, income, citizenship status, and disability information of federal employees and student aid recipients.

The Trump administration opposed the ruling, arguing that it would interfere with the president’s ability to carry out his policies. However, the judge said that the order stops DOGE affiliates from accessing personal information they do not need for their work.

The White House has not yet responded to the ruling.
