Nearly 40 years before the Obama White House denounced the WikiLeaks website for publishing classified documents, another president, Richard Nixon, was even more obsessed with the same phenomenon. Only Nixon and his top aides went to far greater lengths to deal with the problem: They launched an extraordinary campaign to smear and discredit the journalist who, more than anyone else, was bedeviling them by publishing government secrets: newspaper columnist Jack Anderson. The White House obsession with Anderson - whose Washington Merry Go-Round" column was the WikiLeaks of its day - is detailed in a new book being published this month, Poisoning the Press: Richard Nixon, Jack Anderson and the Rise of Washington's Scandal Culture, by journalism professor Mark Feldstein. The book relies in part on newly unearthed tapes from the National Archives that document how Nixon's aides plotted to destroy Anderson by planting forged evidence with him and spreading false rumors about his sex life and that of one of his associates. Feldstein also has uncovered new evidence that documents one of the more outrageous schemes of the Nixon presidency: a plot to assassinate Anderson by either putting poison in his medicine cabinet or exposing him to a "massive dose" of LSD by smearing it on the steering wheel of his car.
