The U.S. Treasury Department has cut contracts with Booz Allen Hamilton after a former contractor leaked tax information about wealthy individuals, including Donald Trump. The contractor, Charles Edward Littlejohn, was sentenced to five years in prison in 2024. He had leaked data to The New York Times and ProPublica between 2018 and 2020. Prosecutors described the leaks as unprecedented in IRS history. Treasury Secretary Scott Bessent stated the firm failed to safeguard sensitive data. Booz Allen Hamilton has 31 contracts with the Treasury, totaling $21 million. The firm has not commented on the matter.
