sentences:  Griswold persuaded three Supreme Court justices to vote to stop "The New York Times" from continuing to publish the Pentagon Papers, an order known as "prior restraint" that has been held to be illegal under the First Amendment to the U.S. Constitution.The papers were simultaneously published in "The Washington Post", effectively nullifying the effect of the prior restraint order.In 1989, Griswold admitted there had been no national security damage resulting from publication.
