The Internal Revenue Service issued a rare apology to billionaire Ken Griffin over the leak of his tax returns to the press, following a settlement of a lawsuit he filed against the IRS. The lawsuit alleged that an IRS employee illegally leaked his tax returns to ProPublica. This incident is part of a larger scandal in which thousands of wealthy Americans had their tax data leaked by government contractor Charles Littlejohn, who was sentenced to five years in prison. The IRS admitted fault and promised to strengthen its data security measures to prevent future breaches. Griffin's lawyer emphasized the importance of holding the IRS accountable, while Griffin himself expressed gratitude for the outcome. This high-profile case highlights the need for increased vigilance in safeguarding taxpayer information.
