President Donald Trump filed a $10 billion lawsuit against the IRS and Treasury Department as one of the plaintiffs on Thursday, alleging a former IRS employee leaked his confidential tax records over six years ago. The federal lawsuit, filed in the Southern District of Florida, accuses the IRS and Treasury of failing to prevent the tax return leak carried out by Charles “Chaz” Littlejohn. The former IRS employee illegally accessed and disclosed the tax records to liberal news outlets in 2019 and 2020. “Defendants had a duty to safeguard and protect Plaintiffs’ confidential tax returns and related tax return information from such unauthorized inspection and public disclosure,” the 27-page lawsuit states. He pleaded guilty to one count of disclosure of tax return information in October 2023 after being charged by the Biden administration the month before.
