Full resignation letter from Demetre C. Daskalakis, a CDC leader, does not hold back.
"The recent shooting at CDC is not why I am resigning. My grandfather, who I am named after, stood up to fascist forces in Greece and lost his life doing so. I am resigning to make him and his legacy proud."
My resignation letter from CDC.  

Dear Dr. Houry,

I am writing to formally resign from my position as Director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention (CDC), effective August 28, 2025, close of business.   I am happy to stay on for two weeks to provide transition, if requested.

This decision has not come easily, as I deeply value the work that the CDC does in safeguarding public health and am proud of my contributions to that critical mission. However, after much contemplation and reflection on recent developments and perspectives brought to light by Secretary Robert F. Kennedy Jr., I find that the views he and his staff have shared challenge my ability to continue in my current role at the agency and in the service of the health of the American people. Enough is enough.

While I hold immense respect for the institution and my colleagues, I believe that it is imperative to align my professional responsibilities to my system of ethics and my understanding of the science of infectious disease, immunology, and my promise to serve the American people.  This step is necessary to ensure that I can contribute effectively in a capacity that allows me to remain true to my principles.

The recent change in the adult and children’s immunization schedule threaten the lives of the youngest Americans and pregnant people.   The data analyses that supported this decision have never been shared with CDC despite my respectful requests to HHS and other leadership.  This lack of meaningful engagement was further compounded by a “frequently asked questions” document written to support the Secretary’s directive that was circulated by HHS without input from CDC subject matter experts and that cited studies that did not support the conclusions that were attributed to these authors.  Having worked in local and national public health for years, I have never experienced such radical non-transparency, nor have I seen such unskilled manipulation of data to achieve a political end rather than the good of the American people.

It is untenable to serve in an organization that is not afforded the opportunity to discuss decisions of scientific and public health importance released under the moniker of CDC.  The lack of communication by HHS and other CDC political leadership that culminates in social media posts announcing major policy changes without prior notice demonstrate a disregard of normal communication channels and common sense.  Having to retrofit analyses and policy actions to match inadequately thought-out announcements in poorly scripted videos or page long X posts should not be how organizations responsible for the health of people should function.  Some examples include the announcement of the change in the COVID-19 recommendations for children and pregnant people, the firing of scientists from ACIP by X post and an op-ed rather than direct communication with these valuable experts, the announcement of new ACIP members by X before onboarding and vetting have completed, and the release of term of reference for an ACIP workgroup that ignored all feedback from career staff at CDC.
Their desire to please a political base will result in death and disability of vulnerable children and adults.  Their base should be the people they serve not a political voting bloc.

I have always been first to challenge scientific and public health dogma in my career and was excited by the opportunity to do so again.  I was optimistic that there would be an opportunity to brief the Secretary about key topics such as measles, avian influenza, and the highly coordinated approach to the respiratory virus season.  Such briefings would allow exchange of ideas and a shared path to support the vision of “Making America Healthy Again.”  We are seven months into the new administration, and no CDC subject matter expert from my Center has ever briefed the Secretary.  I am not sure who the Secretary is listening to, but it is quite certainly not to us.  Unvetted and conflicted outside organizations seem to be the sources HHS use over the gold standard science of CDC and other reputable sources.  At a hearing, Secretary Kennedy said that Americans should not take medical advice from him.  To the contrary, an appropriately briefed and inquisitive Secretary should be a source of health information for the people he serves. As it stands now, I must agree with him, that he should not be considered a source of accurate information.

The intentional eroding of trust in low-risk vaccines favoring natural infection and unproven remedies will bring us to a pre-vaccine era where only the strong will survive and many if not all will suffer.  I believe in nutrition and exercise.  I believe in making our food supply healthier, and I also believe in using vaccines to prevent death and disability.  Eugenics plays prominently in the rhetoric being generated and is derivative of a legacy that good medicine and science should continue to shun. The recent shooting at CDC is not why I am resigning.  My grandfather, who I am named after, stood up to fascist forces in Greece and lost his life doing so.  I am resigning to make him and his legacy proud.   I am resigning because of the cowardice of a leader that cannot admit that HIS and his minions’ words over decades created an environment where violence like this can occur.  I reject his and his colleagues’ thoughts and prayers, and advise they direct those to people that they have not actively harmed.

For decades, I have been a trusted voice for the LGBTQ community when it comes to critical health topics.  I must also cite the recklessness of the administration in their efforts to erase transgender populations, cease critical domestic and international HIV programming, and terminate key research to support equity as part of my decision.

Public health is not merely about the health of the individual, but it is about the health of the community, the nation, the world. The nation’s health security is at risk and is in the hands of people focusing on ideological self-interest.

I want to express my heartfelt gratitude for the opportunities for growth, learning, and collaboration that I have been afforded during my time at the CDC. It has been a privilege to work alongside such dedicated professionals who are committed to improving the health and well-being of communities across the nation even when under attack from within both physically and psychologically.

Thank you once again for the support and guidance I have received from you and previous CDC leadership throughout my tenure. I wish the CDC continued success in its vital mission and that HHS reverse its dangerous course to dismantle public health as a practice and as an institution.  If they continue the current path, they risk our personal well-being and the security of the United States.

🚨🚨 Deranged letter from Education Secretary Linda McMahon to Harvard’s president, cutting off federal funding for any new grants.

Worth reading in full. It is NUTS.
THE SECRETARY OF EDUCATION
WASHINGTON, DC 20202
May 5, 2025
Dr. Alan Garber
Office of the President
Harvard University
Massachusetts Hall
Cambridge, MA 02138
Dr. Garber,
The Federal Government has a sacred responsibility to be a wise and important steward of American taxpayer dollars. Harvard University, despite amassing a largely tax-free $53.2 billion dollar endowment (larger than the GDP of 100 countries), receives billions of dollars of taxpayer largess each year. Receiving such taxpayer funds is a privilege, not a right. Yet instead of using these funds to advance the education of its students, Harvard is engaging in a systemic pattern of violating federal law. Where do many of these "students" come from, who are they, how do they get into Harvard, or even into our country—and why is there so much HATE? These are questions that must be answered, among many more, but the biggest question of all is, why will Harvard not give straightforward answers to the American public?
Harvard University has made a mockery of this country's higher education system. It has invited foreign students, who engage in violent behavior and show contempt for the United States of America, to its campus. In every way, Harvard has failed to abide by its legal obligations, its ethical and fiduciary duties, its transparency responsibilities, and any semblance of academic rigor. It had scrapped standardized testing requirements and a normalized grading system. This year Harvard was forced to adopt an embarrassing "remedial math" program for undergraduates.
Why is it, we ask, that Harvard has to teach simple and basic mathematics, when it is supposedly so hard to get into this "acclaimed university"? Who is getting in under such a low standard when others, with fabulous grades and a great understanding of the highest levels of mathematics, are being rejected?
Harvard has even been embroiled in humiliating plagiarism scandals, exposed clearly and plainly in the media, with respect to your then… running the institution in a totally chaotic way. Harvard alumnus and highly successful hedge fund manager Bill Ackman noted that, under her leadership, Harvard has become "a political advocacy organization for one party."
Ackman has called for the resignation of Pritzker, concluding that the "[t)he mismanagement here is Penny Pritzker" and noting that any serious corporation would have removed her after a litany of recent failings and the fact that, incredibly, "Harvard is not in a good financial position." According to Ackman, one of the world's foremost finance experts, Harvard's so-called S53 billion endowment is "massively overstated as far as what it's really worth," and Harvard has irresponsibly taken out $8 billion in debt.
If this is true, it is concerning evidence of Harvard's disastrous mismanagement, indicating an urgent need for massive reform-not continued taxpayer investment. If Harvard prefers not to change, then Harvard should have no problem using its overflowing endowment to fund its bloated bureaucracy.
At its best, a university should fulfill the highest ideals of our Nation, and enlighten the thousands of hopeful students who walk through its magnificent gates. But Harvard has betrayed this ideal.
Perhaps most alarmingly, Harvard has failed to abide by the United States Supreme Court's ruling demanding that it end its racial preferencing, and continues to engage in ugly racism in its undergraduate and graduate schools, and even within the Harvard Law Review itself. Our universities should be bastions of merit that reward and celebrate excellence and achievement.
They should not be incubators of discrimination that encourage resentment and instill grievance and racism into our wonderful young Americans.
The above concerns are only a fraction of the long list of Harvard's consistent violations of its own legal duties. Given these and other concerning allegations, this letter is to inform you that Harvard should no longer seek GRANTS from the fede… Federal Agencies. The Administration's priorities have not changed and today's letter marks the end of new grants for the University.
These requests will advance the best interests of Harvard University, so it can reclaim its status as a respected educational institution for the future leaders of America. Thank you for your attention to this matter!
Sincerely,
Linda E. McMahon
Secretary of Education
