Alex Haley, Nobile criticized his noted novel, Roots (1976), in an article in the Village Voice, calling it a "hoax" and suggesting his Pulitzer Prize should be rescinded. Clarence Page responded in the Chicago Tribune that Nobile was missing the point of the effect of Haley's work and noted that the author had always said parts were fiction. Page wrote, "I think he [Nobile] missed the larger, more important truth. If "Roots" was a hoax, it was a hoax Americans wanted desperately to believe, which says something more important about Americans than anything Nobile says about Haley." His 2013 New York Post article asserted that President John Kennedy and Jackie Kennedy had sex on Air Force One on the day before his assassination. He based this report on a conversation he had with Kennedy biographer William Manchester, who did not want to be revealed as the source while he was alive. Nobile claimed that Jackie Kennedy Onassis suppressed publication of his book on the president's "Don Juanism" while she was an editor at Doubleday. History teacher Beginning in September 2001, Nobile has also taught history and political science for years at the Cobble Hill School Of American Studies, a public high school located in Brooklyn, managed by the New York City Department of Education. Cobble Hill School controversy In 2004, Nobile made allegation of what was termed a scandal that involved administrators' tampering with test and Regents examinations scores at the Cobble Hill School. As a result of Nobile's "whistleblowing," the Education Department assigned the case to Louis N. Scarcella, a retired police detective who then worked for the school system. In 2004 it published his 30-page report that alleged Theresa Capra, Cobble Hill School's assistant principal of humanities, had tampered with scores and the principal Lennel George had covered up. Capra resigned during the investigation and denied the allegations. George was reassigned. In 2005, Richard J. Condon, the special commissioner of investigation for New York City schools, separately investigated the events at Cobble Hill. The result of his 23-month investigation was a 2007 report that, according to the New York Times, referred to Nobile as “a subpar teacher with poor evaluations who wrongly accused Ms. Capra of engineering a cheating scheme because she had given him a negative review that could have led to his firing.” (After the first investigation, he gained tenure.) The report blamed investigator Scarcella for
