WASHINGTON, Nov 19 (Reuters) - A New York Times report of a former anti-abortion leader's claim that he was told in advance about the outcome of a major 2014 U.S. Supreme Court case involving contraceptives triggered calls on Saturday for an investigation of a court still reeling from the leak of a landmark abortion rights ruling. Rob Schenck was quoted by The Times as saying he was informed weeks before the public announcement of the 2014 ruling shortly after two conservative allies had dinner at the home of Supreme Court Justice Samuel Alito and his wife. Alito said in a statement that any allegation that he or his wife leaked the 2014 decision was "completely false." Alito had called the Roe leak, which was confirmed when the ruling was announced in June, a "grave betrayal." Schenck said one of the Wrights then told him that Alito had authored the Hobby Lobby opinion and that it would be in its favor, The Times said.
