Appeals court says tax-exempt groups can keep political donors secret WASHINGTON (Reuters) - A federal appeals court ruled on Tuesday that tax-exempt organizations do not need to release the names of those who pay for political ads leading up to the November 6 election, turning aside an attempt by a Democratic congressman to force disclosure. The decision reverses a ruling by a lower court in March, and it came four days after a three-judge panel heard oral arguments in the matter. Reporting by David Ingram; Editing by David Brunnstrom
