President Donald Trump filed suit on Thursday against the US Internal Revenue Service (IRS), seeking $10 billion over alleged leaked tax returns he claims harmed his business. The tax documents were leaked to the press by Charles “Chaz” Littlejohn, a former IRS employee from May 2019 through September 2020, according to the lawsuit. “Defendants have caused Plaintiffs’ 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’ public standing,” read the lawsuit filed in Miami federal court. Littlejohn, in 2023, pleaded guilty to releasing Trump’s tax returns and is currently serving a five-year sentence. This is not the first time the president has filed a legal claim against the federal government he oversees.
