ARGUMENT: CLEAR AND PRESENT DANGERWe Ran the C.D.C.: Kennedy Is Endangering Every American’s Health

Published 4 September 2025

Nine former leaders of the Centers for Disease Control and Prevention (CDC), who served as directors or acting directors under Republican and Democratic administrations, serving under presidents from Jimmy Carter to Donald Trrump, argue that HHS Secretary Roert F. Kennedy Jr. poses a clear and present danger to the health of Americans. He has placed anti-vaxxers and conspiracy theorists at top HHS positions, and he appears to be guided by a hostility to science and a belief in bizarre, unscientific approaches to public health.

Richard Besser, Mandy K. Cohen, William Foege, Tom Frieden, Jeffrey Koplan, William Roper, David Satcher, Anne Schuchat, and Rochelle P. Walensky led the Centers for Disease Control and Prevention (CDC) as directors or acting directors under Republican and Democratic administrations, serving under presidents from Jimmy Carter to Donald Trrump.

They argue that HHS Secretary Roert F. Kennedy Jr. poses a clear and present danger to the health of Americans. He has placed anti-vaxxers and conspiracy theorists at top HHS positions, and he appears to be guided by a hostility to science and a belief in bizarre, unscientific approaches to public health.

They write:

What the health and human services secretary, Robert F. Kennedy Jr., has done to the C.D.C. and to our nation’s public health system over the past several months — culminating in his decision to fire Susan Monarez as C.D.C. director days ago — is unlike anything we had ever seen at the agency and unlike anything our country had ever experienced.

Mr. Kennedy has fired thousands of federal health workers and severely weakened programs designed to protect Americans from cancer, heart attacks, strokes, lead poisoning, injury, violence and more. Amid the largest measles outbreak in the United States in a generation, he’s focused on unproven treatments while downplaying vaccines. He canceled investments in promising medical research that will leave us ill prepared for future health emergencies. He replaced experts on federal health advisory committees with unqualified individuals who share his dangerous and unscientific views. He announced the end of U.S. support for global vaccination programs that protect millions of children and keep Americans safe, citing flawed research and making inaccurate statements. And he championed federal legislation that will cause millions of people with health insurance through Medicaid to lose their coverage. Firing Dr. Monarez — which led to the resignations of top C.D.C. officials — adds considerable fuel to this raging fire.
