I am profoundly disturbed by the ejection of Steven Kahn and his colleagues from the American Diabetes Association’s meeting as they handed out copies of their op-ed criticizing the Trump administration’s devastating damage to American biomedical research. Director Bhattacharya promised to foster open dialogue and debate in science. Instead, he is presiding over an environment where dissent has no place and scientists who dare criticize the regime are cast out. Director Bhattacharya, other HHS and NIH leadership, and the leadership of the American Diabetes Association must immediately explain what their roles were in the ejection of Dr. Kahn and his colleagues, and anyone involved in what appears to be a blatant act of political censorship must be held accountable. Censorship and intimidation have no place in science. Discovery, innovation, and the millions of patients who are waiting for cures demand curiosity-driven science, free from political interference.
