This action follows the conviction of a former contractor who stole and leaked tax information belonging to Trump and other wealthy individuals. US President Donald Trump filed a $10 billion lawsuit against the IRS and the Treasury Department on Thursday, alleging the federal agencies failed to safeguard his private financial data from a massive leak that occurred during his first administration. The complaint, filed in a Florida federal court, names the president’s adult sons, Donald Trump Jr. and Eric Trump, along with the Trump Organisation as co-plaintiffs. The lawsuit follows a major policy shift at the Treasury Department. Spokespeople for the White House, the Treasury Department, and the IRS were not immediately available for comment late Thursday.
