New York Comptroller Thomas DiNapoli, seeking greater disclosure of corporate political donations, sued Oracle, demanding that the world's largest database maker reveal its political spending records. DiNapoli, a Democrat backed by labor unions, has been using his position as the sole trustee of New York's $184.5 billion fund to press corporations to make their donations public after the Supreme Court's 2010 ruling in Citizens United allowed companies to make political gifts without limitations.
