In 1952, the US banned novelist Graham Greene from entering the United States, citing his youthful membership in the Communist party. Greene was a critic of US foreign policy. Documents reveal though that US officials thought the ban made the US look bad. “They conceded that he had been a member of the British Communist party for only four weeks when a 19-year-old student, ‘as a joke’. They admitted his writing clearly showed that he was anti-communist, according to the documents obtained by the Guardian under the US Freedom of Information Act.”
