An anonymous reader writes "According to an International Herald Tribune article, the Smithsonian pre-emptively toned down the scientific content of a climate change exhibit put into place last year. The changes, including removal of scientist conclusions and muddying of displayed data, were made to ensure that the exhibit would not offend the Congress or the White House. Pressure brought to bear by Institute officials resulted in the resignation of Robert Sullivan, a sixteen year veteran of the organization. 'This is not the first time the Smithsonian has been accused of taking politics into consideration. The congressionally chartered institution scaled down a 1995 exhibit of the restored Enola Gay, the B-29 that dropped the atomic bomb on Hiroshima, after veterans complained it focused too much on the damage and deaths. Amid the oil-drilling debate in 2003, a photo exhibit of Alaska's Arctic National Wildlife Refuge was moved to a less prominent space.'"
