President Donald Trump, joined by sons Donald Trump Jr. and Eric Trump along with the Trump Organization, filed a blockbuster $10 billion lawsuit Thursday in Miami federal court against the Internal Revenue Service and U.S. Treasury Department. The civil complaint accuses the agencies of failing to safeguard confidential tax records leaked by former IRS contractor Charles Littlejohn in 2019 and 2020 to outlets including The New York Times and ProPublica.

The suit, docketed as Trump v. Internal Revenue Service, 26-cv-20609 in U.S. District Court for the Southern District of Florida, demands at least $10 billion for reputational harm, financial losses, public embarrassment, and tarnished business standing. “The IRS wrongly allowed a rogue, politically-motivated employee to leak private and confidential information about President Trump, his family, and the Trump Organization to the New York Times, ProPublica and other left-wing news outlets,” a Trump legal team spokesman stated, as reported by CNBC.

Littlejohn, a Booz Allen Hamilton contractor, pleaded guilty in October 2023 to unauthorized disclosure of tax return information and received the maximum five-year prison sentence in January 2024 from U.S. District Judge Ana C. Reyes, who called his actions “an attack on our constitutional democracy,” according to CBS News. Prosecutors noted Littlejohn targeted Trump data specifically, using broad searches to evade detection while leaking records on thousands including Jeff Bezos and Elon Musk.

The Leaker’s Path and Massive Breach

Littlejohn’s leaks fueled high-profile reporting: The New York Times revealed Trump paid $750 in federal income taxes in 2016 and 2017, and zero in 10 of the prior 15 years due to losses offsetting income. ProPublica received data on Trump’s businesses and wealthy individuals, prompting claims of inconsistencies from experts like UC Berkeley’s Nancy Wallace. The breach affected roughly 406,000 taxpayers, per IRS estimates cited by the Treasury Department.

In a 2024 deposition, Littlejohn admitted the Trump materials included “all businesses that he had owned,” per the lawsuit. Trump lawyer Alejandro Brito argued the agencies neglected “mandatory precautions” to prevent such breaches, causing profound damage. Neither IRS nor Treasury responded to comment requests from multiple outlets including NBC News and ABC News.

The timing intensifies scrutiny: Just three days prior, Treasury Secretary Scott Bessent announced cancellation of all department contracts with Booz Allen Hamilton—31 deals worth $4.8 million annually and $21 million total—blaming inadequate safeguards. “Booz Allen failed to implement adequate safeguards to protect sensitive data, including the confidential taxpayer information it had access to through its contracts with the Internal Revenue Service,” Bessent stated in a Treasury press release, as covered by U.S. Department of the Treasury.

Booz Allen Fallout and Administration Retribution

Booz Allen’s stock plunged over 10% post-announcement. The firm countered: “Booz Allen stores no taxpayer data on its systems and has no ability to monitor activity on government networks,” and claimed full cooperation in Littlejohn’s prosecution, per CNBC. Bessent framed the move as rooting out waste: “President Trump has entrusted his cabinet to root out waste, fraud, and abuse, and canceling these contracts is an essential step to increasing Americans’ trust in government.”

This suit marks a rare instance of a sitting president suing his own administration personally, not officially. Legal experts question viability under sovereign immunity, which typically shields federal agencies unless waived. The $10 billion figure dwarfs prior Trump claims, like a $230 million DOJ demand for past probes into Russia ties and Mar-a-Lago search, filed via administrative claims in 2023-2024, as detailed by The New York Times.

Trump alluded to such claims last year: “I have a lawsuit that was doing very well, and when I became president I said, ‘I’m sort of suing myself.'” The pattern underscores Trump’s strategy of counteroffensives against perceived weaponization of government, from IRS audits to FBI raids.

Legal Hurdles and Broader IRS Battles

Filing in Miami—Trump’s home turf—may seek a sympathetic venue, but federal courts often dismiss suits against agencies for lack of consent to be sued. Bloomberg Tax noted the complaint alleges negligence in protecting data under laws like Section 7213(a)(1), the statute Littlejohn violated. House Judiciary Republicans previously probed Littlejohn’s plea deal as too lenient, per their 2025 letter.

X posts from January 30 reflected buzz: Users shared CNBC links, with one noting, “President Trump continues to hold those who wrong America and Americans accountable.” No direct posts from Trump or sons appeared in searches.

The case revives Trump’s long IRS feud, from refusing returns release to whistleblower claims of audit interference. ProPublica stories alleged Trump undervalued assets for taxes while inflating for lenders, though no charges resulted. This lawsuit positions Trump as victim, demanding accountability amid his pledges to overhaul the IRS.

Implications for Tax Privacy and Government Accountability

If pursued, the suit could force disclosures on IRS security lapses, echoing post-leak reforms. Littlejohn stored data on personal devices like an iPod, prosecutors said. Success might embolden suits by other leak victims like Musk or Bezos, though massive damages seem aspirational.

For industry insiders, watch jurisdictional challenges and potential motions to dismiss. Trump’s legal team eyes punitive measures, aligning with administration actions like Booz Allen cuts.
