You might find this passage interesting:
While the history of this matter is not before the Committee, it is well known that these charges were commenced only after Professor Churchill had published some highly controversial essays dealing with, among other things, the 9/11 tragedy. While not endorsing either the tone or the contents of those essays, the Committee reaffirms, as the University has already acknowledged, that Professor Churchill had a protected right to publish his views. In the Committee’s opinion, his right to do so was protected by both the First and Fourteenth Amendment guarantees of free speech. The aggressive pursuit of knowledge cannot proceed unless scientists, social scientists, and other researchers are permitted—and indeed encouraged—to present alternative and sometimes heretical positions and to seek to defend them in the court of academic opinion. Thus, the fact that Professor Churchill published those controversial essays was not part of the charge to the Committee and played absolutely no role in its deliberations.
