President Donald Trump, alongside his sons Donald Trump Jr. and Eric Trump, and the Trump Organization, has filed a lawsuit seeking at least $10 billion from the Internal Revenue Service (IRS) and the Department of the Treasury. The suit, lodged in a Florida federal court on January 29, 2026, centers on the alleged unlawful disclosure of confidential tax returns.
The core of the legal challenge hinges on the claim that these federal agencies failed to implement adequate safeguards, allowing a former IRS contractor, Charles Littlejohn, to illegally obtain and disseminate Trump's tax information to news organizations, including The New York Times and ProPublica, between May 2019 and September 2020. Littlejohn, who has since pleaded guilty and is serving a five-year prison sentence, was employed by Booz Allen Hamilton. The lawsuit asserts that the IRS and Treasury were negligent or grossly negligent in their duty to protect this sensitive data, leading to significant alleged "reputational and financial harm, public embarrassment, unfairly tarnished their business reputations, portrayed them in a false light, and negatively affected President Trump" and the other plaintiffs.

Agency Response and Legal Maneuvering
In the wake of the leak, the Treasury Department has cited Littlejohn's actions and consequently canceled all contracts with Booz Allen Hamilton, stating the firm "failed to implement adequate safeguards to protect sensitive data." The lawsuit itself alleges the disclosures were made "knowingly—or at the very least negligently or with gross negligence."
Trump's legal team has also requested a 90-day pause in the proceedings while engaging in talks with the IRS to resolve the lawsuit. This move raises questions about potential conflicts of interest, with critics noting that Trump, as president, controls both sides of the litigation. Watchdog groups and some legal observers have pointed to the extraordinary nature of a president suing agencies within his own administration, suggesting the possibility of "collusive litigation tactics" and questioning whether the Department of Justice will "zealously defend the public fisc."

Background of the Leaks and Lawsuit
This legal action follows the criminal conviction of Charles Littlejohn in 2023 for leaking tax data belonging to thousands of Americans, including Trump's. Trump notably did not publicly release his tax returns during his presidential campaigns, a departure from past presidential candidates. Reports suggest that despite the alleged harm, Trump's net worth may have increased since the leaks, complicating claims of financial damages. The suit is one in a long history of legal actions involving Trump and government funding or institutions.
