A former National Security Council official said Monday that the White House tried to silence his criticism of its Middle East policies by ordering the CIA to censor an op-ed column he wrote. Flynt Leverett, a former senior director for Middle East affairs at the National Security Council, or NSC, and a former CIA analyst, said the White House told a CIA censor board to excise parts of a 1,000-word commentary on U.S. policy toward Iran that he had offered to the New York Times. He said the agency's action was fabricated to silence an established critic of the administration's foreign policy incompetence at a moment when the White House is working hard to fend off political pressure to take a different approach." Leverett said there were two key paragraphs that the CIA board wanted to cut. The first was about U.S. cooperation with Iran concerning Afghanistan about the time of the Sept. 11 attacks in 2001. The second dealt with an offer by Iran to the United States in early 2003 to discuss the possibility of a "grand bargain" that would settle several disputes between the two countries. He said both episodes had been publicly discussed by former Secretary of State Colin L. Powell and his former deputy, Richard L. Armitage. "There is no basis for claiming that these issues are classified and not already in the public domain," he said. Like other former CIA employees, he is required to submit manuscripts for articles, books and speeches to the agency for review.
