Mayo Clinic Faces Lawsuit Over AI Compliance Retaliation Claims

Former compliance leader alleges wrongful termination

Mayo Clinic is facing a federal lawsuit from a former artificial intelligence compliance leader who claims the health system retaliated against her after she raised concerns about patient data handling and research safety protocols.

Traci Tamiko Eto filed the complaint in Minnesota U.S. District Court on July 7, 2026, alleging violations of the Family and Medical Leave Act and Americans with Disabilities Act. The Rochester Post Bulletin first reported the lawsuit details.

Eto joined Mayo Clinic in December 2023 as director of research operations, bringing 18 years of experience in protecting human research subjects. According to the complaint, she was designated to lead Mayo's alignment with the Biden Administration's October 2023 Executive Order on AI security and privacy safeguards.

Multiple compliance concerns raised

The lawsuit details several instances where Eto allegedly identified problems with Mayo's AI research practices. In mid-2024, she raised concerns about de-identification processes within Mayo Clinic Platform, a healthcare AI hub that uses patient data from Mayo and other institutions.

According to the complaint, Eto detected that certain data-sharing processes with global providers had not received proper Institutional Review Board oversight. When she reported this to her supervisor Jeffrey Schmoll and IRB chair Scott Wright, the lawsuit alleges Wright resisted her concerns, stating that IRB review would "jeopardize the pace of ongoing research projects" and "compromise Mayo's competitive advantage."

In November 2024, Eto flagged issues with a study on MAYA, a digital assistant tool. The lawsuit claims the research team mischaracterized findings and used unauthorized software. The complaint alleges the MAYA project had a 67% error rate that investigators attempted to disguise, and that ten separate whistleblower reports raised similar alarms.

Why it matters

This case highlights the tension between rapid AI development in healthcare and regulatory compliance. As health systems race to implement AI technologies, the lawsuit raises questions about whether patient safety and privacy protections are being adequately maintained. The allegations suggest potential conflicts between commercial pressures and ethical research standards in medical AI development.

Demotion and termination timeline

After Eto reported two misconduct instances to Mayo's legal department in February 2025, she was allegedly excluded from executive meetings. She received a pay raise in March 2025, but two weeks later was told to resign or face career-damaging consequences, according to the complaint.

Eto was demoted in July 2025, losing supervision of 39 subordinates. She subsequently took FMLA leave for depression. On September 2, 2025, while still on leave, Mayo notified her that her position was being eliminated. The health system terminated her employment on December 1, 2025.

The lawsuit claims Eto's job was the only one eliminated in the supposed reduction in force. Despite applying for 15 internal positions, she received only one interview. The complaint also alleges Mayo uses a "ghost file" system that flags employees who raised compliance concerns as "Not Eligible for Rehire" in external verification systems.

Eto is requesting a jury trial and seeking back pay, front pay, lost benefits, damages, and litigation costs. Mayo Clinic had not responded to the complaint in court at the time of the Post Bulletin's report.

"The Mayo Clinic made the deliberate choice to put profit first, over patient privacy, and in one egregious instance, patient safety," said Arthur Davis of HKM Employment Attorneys, the firm representing Eto.

The Rochester Post Bulletin first reported these details.
