David Gergen, who had worked in the White House during the Richard Nixon and three subsequent administrations, said in his 2000 memoir, "Eyewitness to Power", of Woodward's reporting, "I don't accept everything he writes as gospel—he can get details wrong—but generally, his accounts in both his books and in the Post are remarkably reliable and demand serious attention. I am convinced he writes only what he believes to be true or has been reliably told to be true. And he is certainly a force for keeping the government honest."
