The group joined a lawsuit filed in May that sought to block the proposed $1.8 billion "Anti-Weaponization Fund," which the Trump administration later scrapped after bipartisan pushback. The updated lawsuit, filed by legal advocacy group Democracy Forward, now also targets the audit immunity deal conferred on the president, his sons and the Trump Organization, which remains in place. The updated lawsuit says Trump and his family are "obligated to pay taxes owed, just like every other taxpayer." The case alleges the agreement violates a law that bars the president from interfering with tax audits. The judge overseeing the case, U.S. District Judge Leonie Brinkema in Alexandria, Virginia, blocked the administration in May from proceeding with the fund.
