It is a lawsuit that reads less like a legal complaint and more like a declaration of war against the Deep State. Former President Donald Trump and his two eldest sons have launched a ballistic missile at the federal government, filing a staggering $10 billion claim against the US Treasury and the IRS for what they describe as a "calculated political assassination" via data leakage.

The filing, lodged in a federal court in Washington D.C., accuses the agencies of gross negligence and "malicious intent" in failing to safeguard the former First Family’s private tax records. The suit stems from the actions of Charles Littlejohn, a rogue IRS contractor who leaked thousands of Trump’s tax documents to The New York Times and ProPublica—an act a federal judge previously branded "an attack on our constitutional democracy."

"The Weaponization of Data"

For years, Trump’s tax returns were the Holy Grail for his political adversaries. When they finally surfaced, they painted a picture of complex maneuvering and disputed valuations. But for the Trump legal team, the content is irrelevant; the crime is the breach itself. "This was not a leak; it was a flood unleashed by partisans within the machinery of state," a source close to the Trump legal team told this bureau.

The lawsuit alleges that the IRS "systematically dismantled" its own internal firewalls, allowing Littlejohn to exfiltrate data on an industrial scale. The plaintiffs argue that this breach has caused irreparable reputational damage and compromised the Trump Organization’s global business dealings.

• The Littlejohn Factor: Charles Littlejohn, now serving a five-year prison sentence, admitted to stealing the data to "expose" the President. Trump’s lawyers argue the IRS culpability didn’t end with his arrest—it began with their failure to stop him.
• The $10 Billion Question: Legal experts suggest the astronomical damages figure is designed to grab headlines rather than reflect actual provable losses, yet it signals Trump’s intent to keep the "weaponization of justice" narrative front and center.

A Precedent in the Making

If this case proceeds to discovery, it could pry open the secretive inner workings of the IRS, exposing exactly how the agency handles the data of high-profile targets. It is a high-stakes gamble: the government will likely claim sovereign immunity, but Trump is betting that the court of public opinion will rule in his favor long before a judge does.

"They thought they could use the tax code as a bludgeon," Trump stated in a furious communiqué from Mar-a-Lago. "Now they will pay the price for their treachery." As the 2026 news cycle spins up, this lawsuit ensures that Trump’s war with the Washington establishment is far from over.
