American Diabetes Association (ADA) CEO Charles Henderson issued a formal apology on Wednesday following the removal of five prominent medical researchers from the organization’s annual scientific sessions in New Orleans. The incident, which occurred on June 21, involved the expulsion of physicians who were distributing an editorial criticizing federal research funding policies.
Why were the researchers removed from the conference?
The five physicians—Dr. Steven Kahn, Dr. Desmond Schatz, Dr. Aaron Kelly, Dr. Maureen Gannon, and Dr. Justin Ryder—were escorted from the convention center by security and police after distributing copies of an editorial they had authored. The document, published in an ADA journal, voiced concerns regarding the National Institutes of Health (NIH) grant-making processes and overall research funding levels.
According to the American Diabetes Association, the organization initially defended the expulsion by citing internal policies and tax-exempt status regulations governing 501(c)(3) entities. However, the move sparked significant backlash within the medical community, with many members characterizing the action as an attempt to suppress professional dissent regarding federal health policy.
How did the ADA leadership respond?
In a video statement released five days after the event, Henderson apologized directly to the five physicians and the broader diabetes community. "I recognize the impact that experience had on each of you. I am deeply sorry for the hurt, frustration, and the pain that resulted," Henderson stated.
The CEO acknowledged that the organization’s initial response, which relied on legalistic justifications, failed to address the concerns of its membership. Henderson announced that the ADA has commissioned an independent review of the events that took place on June 21, as well as an audit of the organization’s subsequent communications. He stated that the goal of this review is to restore trust and ensure that the ADA remains a forum for scientific discourse.
What is the broader impact on medical advocacy?
The incident has highlighted the tension between professional medical societies and their role in political or policy advocacy. The editorial in question specifically addressed the National Institutes of Health, which provides the majority of federal funding for diabetes research in the United States.

The controversy gained momentum as prominent members, including former ADA president Dr. John Buse, publicly criticized the decision to involve security. Buse stated that the apology is a "great first step" but noted that the organization must now provide explicit clarification regarding the rights of its members to engage in advocacy during scientific meetings.
