“Secretary Robert F. Kennedy Jr. has turned his back on science, on public health, and on the American people – spreading conspiracies and lies, driving up costs, and putting lives at risk,” Stevens said in a news release on Wednesday announcing the move.

“Under his watch, families are less safe and less healthy, people are paying more for care, lifesaving research has been gutted, and vaccines have been restricted. He has driven up health care costs while tearing down the scientific institutions that keep Michiganders and families across America safe. His actions are reckless, his leadership is harmful, and his tenure has become a direct threat to our nation’s health and security. Congress cannot and will not stand by while one man dismantles decades of medical progress.”
