The agency is now without a confirmed leader. According to NBC News and CBS News, Monarez’s firing follows a series of security and leadership concerns. A shooting at the CDC’s Atlanta campus on August 8 left a police officer dead. The gunman left bullet holes in six CDC buildings.

Morale at the agency was already low due to earlier layoffs and restructuring. Monarez canceled a planned safety meeting days before her removal. Several other top officials also resigned this week. The CDC is now facing one of its most unstable periods in recent history.

According to The Washington Post and Reuters, Dr. Debra Houry, Dr. Demetre Daskalakis, Dr. Daniel Jernigan, and Dr. Jen Layden also resigned. Their exits leave key leadership positions vacant.

Reasons Behind Susan Monarez’s Sudden Exit

The exact reason for Monarez’s dismissal has not been confirmed. Official statements from HHS were brief and vague. Sources suggest internal disagreements and ongoing chaos played a role. Monarez tried to reassure staff after the shooting but faced criticism for poor communication.

President Trump nominated Monarez in March. She was seen as a bridge between scientific integrity and administrative reform. However, her lack of a clinical background and strained staff relations may have weakened her position.

Her predecessor nominee, Dr. David Weldon, was pulled due to controversial views on vaccines. Monarez replaced him and was the first CDC director confirmed by the Senate. Still, her tenure lasted less than one month — the shortest in CDC history.

According to CBS News, HHS Secretary Robert F. Kennedy Jr. has begun reshaping the agency. He recently fired members of the vaccine advisory panel and oversaw hundreds of layoffs. The CDC is now at a turning point with no clear successor announced.

The main keyword, “why CDC director ousted,” explains a crisis of leadership, safety concerns, and political tension at the CDC. This change marks a historic low for the agency’s stability.
