Question: Robert Wisden played Richard Nixon on Watchmen which featured characters acquired from what company?
Context: The Richard Nixon Foundation is a not-for-profit organization based at the Richard Nixon Presidential Library and Museum in Yorba Linda, California.  It was founded in August, 1983 by Richard Nixon, 37th President of the United States, and served as the governing body of the Nixon Library for nearly twenty years.  Today it operates the Nixon Library in conjunction with the National Archives and Records Administration, which is an entity of the federal government of the United States, in addition to undertaking charitable and education-based activities. A memorandum known as the Zilch memo was an American government document sent by National Security Advisor Henry Kissinger to President Richard Nixon on January 3, 1972, about the military situation in Laos during the Vietnam War.  On the memo, in his own handwriting, Nixon described the decade-long bombing campaign by the United States in Southeast Asia as a "failure," having achieved "zilch," despite public comments to the contrary.  Just the day before, January 2, Nixon told CBS News reporter Dan Rather in an interview that the bombing was "very, very effective."  Previously missing from the Richard Nixon Library, the memo was discovered in the possession of Alexander Butterfield, who served as the Deputy Assistant to President Nixon from 1969 to 1973, by "Washington Post" reporter Bob Woodward, who subsequently published it in his 2015 book "The Last of the President's Men". Watchmen is an American comic-book limited series published by DC Comics in 1986 and 1987, and collected in 1987.  The series was created by a British collaboration consisting of writer Alan Moore, artist Dave Gibbons, and colorist John Higgins.  "Watchmen" originated from a story proposal Moore submitted to DC featuring superhero characters that the company had acquired from Charlton Comics.  As Moore's proposed story would have left many of the characters unusable for future stories, managing editor Dick Giordano convinced Moore to create original characters instead. "'Monster" is the fourth episode of the second season of the American crime-thriller television series "Millennium".  It premiered on the Fox network in the United States on October 17, 1997.

The Richard Nixon Birthplace is where Richard Nixon was born and lived from 1913 to 1922.  It is located at the Richard Nixon Presidential Library and Museum in Yorba Linda, Orange County, California. Nixon v. General Services Administration, 433 U.S 425 (1977), is a landmark court case concerning the principle of presidential privilege and whether the public is allowed to view a President’s “confidential documents”.  The Presidential Recordings and Materials Preservation Act, signed into law by President Gerald Ford in 1974, ordered that the Administrator of General Services obtain President Richard Nixon’s presidential papers and tape recordings.  In addition, the Act further ordered that government archivists seize these materials.  These archivists would preserve the material deemed historic and return to former President Nixon the materials deemed as private.  Furthermore, this Act stated that material that was preserved could be used in judicial hearings and proceedings.  Immediately after this Act was enacted, Richard Nixon filed a lawsuit in a federal district court claiming that the Act violated the principle of separation of powers, the principle of presidential privilege, Nixon’s personal privacy, his First Amendment right of association, and further asserted that it amounted to a constitutionally prohibited Bill of Attainder.
