Former U.S. President Richard Nixon (C) watches as a Marine honor guard carries the casket of his wife Patricia Nixon up the steps at the Richard Nixon Library in preparation for the viewing by the public, in Yorba Linda, California, in this June 25, 1993 file photo. Nearly 40 years after President Richard Nixon resigned in disgrace because of the Watergate scandal, the debate over how his legacy should be defined seems as vibrant as ever - at Nixon's presidential library, at least. It pits Nixon loyalists who want the library to do more to portray the 37th president as a great leader with a range of domestic and foreign accomplishments, against historians and others who say that the library - as a symbol of U.S. history and education - has a duty to also provide an unvarnished, and unflattering, lesson on Nixon's downfall.
