WASHINGTON — The White House tried to stop a State Department senior intelligence analyst from discussing climate science in congressional testimony this week, internal emails and documents show. The State Department’s Bureau of Intelligence and Research declined to make changes to the proposed testimony and the analyst, Rod Schoonover, an adjunct professor at Georgetown University, was ultimately allowed to speak before the House Permanent Select Committee on Intelligence on Wednesday. But in a highly unusual move, the White House refused to approve Dr. Schoonover’s written testimony for entry into the permanent Congressional Record. The reasoning, according to a June 4 email seen by The New York Times, was that the science did not match the Trump administration’s views. Norman J. Ornstein, a resident scholar at the American Enterprise Institute, a conservative policy group, said that it was common for the White House to vet agency testimony to Congress to ensure it did not contradict administration policy. But, he said, “I have never heard of basic facts being deleted from or blocked from testimony.” Mr. Ornstein said withholding the analyst’s written testimony was significant. A verbal presentation could be interpreted as an individual’s position, he said, but “the written testimony is a more formal expression of a department.”
