Sanders Demands Congress 'Immediately' Investigate Firing of CDC Director
Health and Human Services Secretary Robert F. Kennedy Jr. "must testify," and the CDC officials who were fired and resigned in protest also should be invited to do so, said the senator.
In the wake of a "Wednesday night massacre" at the US Centers for Disease Control and Prevention and related resignations, Sen. Bernie Sanders on Thursday called for an immediate congressional probe.
Just weeks after the Senate confirmed President Donald Trump's pick to lead the CDC, Dr. Susan Monarez, the director was forced out on Wednesday after reportedly clashing with Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. Her ouster led to calls for firing Kennedy, four other officials resigning in protest, and a related walkout by agency staff.
Sanders (I-Vt.) serves as ranking member of the Senate Health, Education, Labor, and Pensions (HELP) Committee, and in a letter, he asked Sen. Bill Cassidy (R-La.), the panel's chair and a physician, to "immediately" call a hearing.
"I am very disturbed that the Trump administration apparently made this reckless decision because Director Monarez refused to act as a rubber stamp to implement Secretary Kennedy's dangerous agenda to substantially limit the use of safe and effective vaccines and undermine the confidence that the American people have in scientific achievements that have saved millions of lives," Sanders wrote to Cassidy.
RFK Jr. is pushing out scientific leaders who refuse to act as a rubber stamp for his dangerous conspiracy theories and manipulate science. Today, I am calling for a bipartisan congressional investigation into the firing of CDC Director Dr. Monarez.

"We need leaders at the CDC and HHS who are committed to improving public health and have the courage to stand up for science," he argued, "not officials who have a history of spreading bogus conspiracy theories and disinformation that will endanger the lives of the American people and people throughout the world."
Sanders—who previously served as the panel's chair—asked Cassidy to launch a "bipartisan probe" and stressed that "as part of that investigation, Secretary Kennedy must testify at a hearing in the HELP Committee as soon as possible. We should also invite Dr. Monarez and the senior CDC officials who resigned to testify as well."
Noting that Cassidy on Wednesday "called for oversight of the firings and resignations at the agency," Sanders made the case that "as a start, the American people should hear directly from Secretary Kennedy and Dr. Monarez and every member of our committee should be able to ask questions and get honest answers from them."
The senator also took aim at the HHS chief, writing that "it is absolutely imperative that trust in vaccine science not be undermined. The well-being of millions of people are at stake. In just six months, Secretary Kennedy has completely upended the process for reviewing and recommending vaccines for the public."
"Enough is enough," he declared. "We have got to make it clear to Secretary Kennedy that his actions to double down on his war on science and disinformation campaign must end. Too many lives are at stake."
In a statement released later Thursday, after the walkout, Sanders applauded CDC workers "for standing up for science and protesting the reckless decision of Secretary Kennedy to push out leading scientists from the agency."
"Speaking up takes real courage," he said. "Now is the time for all of us—whether you are a Democrat, Republican, independent, progressive or conservative—to come together and say enough is enough. Vaccines are one of the greatest public health achievements of the 20th century. We will not stand by silently as Secretary Kennedy takes them away."
"Let us be clear: We are witnessing a full-blown war on science, on public health, and on truth itself," Sanders emphasized. "In just six months, Secretary Kennedy has dismantled the vaccine review process, narrowed access to life-saving Covid vaccines, and filled scientific advisory boards with conspiracy theorists and ideologues. "
Slamming the reported reasons for Monarez's ouster as "outrageous and unacceptable," the senator concluded that "history will not look kindly on those who stayed silent in the face of this assault on science. We have a moral responsibility to act now."
