Amazon de-listed Paul Sperry's book: Amazon removed RealClear Investigations reporter Paul Sperry's 2008 book titled "Infiltration: How Muslim Spies and Subversives have Penetrated Washington." Users who find the link to his book will find a notice that reads "Sorry we couldn't find that page [.] Try searching or go to Amazon's home page." Sperry tweeted about the incident saying "Amazon has secretly de-listed my bestselling book, 'Infiltration' (exposing how Saudi Embassy set up terror fronts and mosques around the Beltway) after I broke stories about the conflicts and biases of the Nat'l Editor & Fact Checker of the Wash Post, owned by AMAZON." The Washington Post and Amazon are both owned by billionare Jeff Bezos.
