Donald Trump, along with his sons Eric Trump and Donald Trump, and The Trump Organization, has filed a $10 billion lawsuit against the United States — Internal Revenue Service and United States — United States Department of the Treasury. The lawsuit, filed in a Florida federal court, alleges that the federal agencies failed to prevent the leak of Donald Trump's confidential tax information to news outlets like The New York Times and ProPublica between 2018 and 2020. This leak was carried out by former United States — Internal Revenue Service contractor Charles Littlejohn, who worked for Booz Allen Hamilton and was later sentenced to five years in prison for the crime. The plaintiffs claim the disclosures caused significant reputational and financial harm, public embarrassment, and negatively affected Donald Trump's public standing and support in the 2020 presidential election. The lawsuit follows the United States — United States Department of the Treasury's decision to cut its contracts with Booz Allen Hamilton, citing the firm's failure to implement adequate safeguards for sensitive data.
