Greg Thielmann served as a top intelligence official at the U.S. State Department until resigning shortly before the war with Iraq and charging the George W. Bush administration with cooking its intelligence.
A graduate of the Woodrow Wilson School of Public and International Affairs at Princeton University, worked for U.S. Congressman John Culver before entering the United States Foreign Service where he has served for more than 25 years, working in arms control and security issues. He was acting director of the Strategic, Proliferation, and Military Affairs Office in the Bureau of Intelligence and Research at the State Department at the time of his retirement.
At the State Department, Thielmann was assigned the task of giving John R. Bolton his daily intelligence briefing. Thielmann has since accused Bolton of cooking the intelligence and refusing to hear intelligence that contradicted his pre-established opinions.
