Sen. Raphael Warnock looked across the hearing room and told the nation’s top health official he was dangerous. “You are a hazard to the health of the American people,” the Georgia Democrat said to HHS Secretary Robert F. Kennedy Jr. during a Senate Finance Committee hearing in May 2026. “You ought to resign.” If Kennedy refused, Warnock added, President Trump should fire him.
The demand came as U.S. measles cases for 2026 approached 1,000, according to the University of Minnesota’s Center for Infectious Disease Research and Policy, with active outbreaks reported in multiple states. It marked the sharpest congressional challenge yet to Kennedy, a longtime vaccine skeptic who was confirmed to lead HHS despite years of public statements questioning the safety of routine childhood immunizations.
A confrontation rooted in rising case counts
In a statement released after the hearing, Warnock tied his call for Kennedy’s removal to what he described as turmoil at the CDC. He argued that instability at the agency has undermined public confidence and slowed the federal response to the measles surge, framing the issue as an urgent matter of public safety rather than a routine policy disagreement.
The numbers behind his alarm are tracked by the CDC’s national measles surveillance system, which reports confirmed cases, the number of jurisdictions with active transmission, and comparative totals from 2025. South Carolina alone recently confirmed 11 new cases. Arizona, Utah, and Michigan have reported clusters tied to schools, health care settings, and community gatherings, illustrating how quickly the virus moves through under-immunized populations.
Warnock is not the only senator pressing the issue. Sen. Angela Alsobrooks of Maryland issued a separate statement calling Kennedy’s decision to delay a key international consultation on the country’s measles elimination status “an utter embarrassment.” Alsobrooks said Kennedy had personally intervened to postpone the meeting, warning that the move could jeopardize the United States’ standing with global health partners and undermine efforts to reassure parents about the value of vaccination.
What elimination status means and why it is at risk
The United States first achieved measles elimination status in 2000, meaning the disease was no longer continuously circulating within national borders. Elimination does not mean zero cases. It means any outbreaks can be traced to importations and brought under control before sustained domestic transmission takes hold.
The formal review process evaluates whether chains of measles transmission have persisted for 12 months or longer, which would threaten the classification. Johns Hopkins Bloomberg School of Public Health has explained that if active transmission crosses that threshold, the country could formally lose its elimination designation, a step that would carry significant reputational and public health consequences.
No federal agency has confirmed a new date for the delayed review or stated whether the postponement is a matter of weeks or months. If the review does not proceed before sustained transmission chains reach the 12-month mark, the question shifts from whether the U.S. will lose its status to when.
International scrutiny intensifies
The World Health Organization has issued a Disease Outbreak News notice classifying the U.S. measles situation as an unusual event with potential significant public health impact, reported under the International Health Regulations framework. The notice highlighted both the rising case count and the geographic spread across multiple states, emphasizing the risk of further international dissemination through travel.
The CDC publishes weekly surveillance tables through its National Notifiable Diseases Surveillance System, tracking imported cases and domestic transmission patterns. The agency’s Morbidity and Mortality Weekly Report previously documented declining vaccination rates and global measles activity as contributing factors in a detailed epidemiological analysis covering early 2025 trends. No equivalent survey for 2026 has been published, leaving a gap in the public record at a moment when vaccination coverage is the single most important variable in predicting whether outbreaks will grow or be contained.
What Kennedy and HHS have not said
Kennedy and HHS have not issued a public response to Warnock’s demand or to Alsobrooks’s criticism. Without a statement from Kennedy’s office, the specific reasons for postponing the elimination review remain unclear. No official CDC or HHS document in the public record explains the scheduling decision or provides an alternative rationale.
Other Finance Committee members used the hearing to press Kennedy on staffing vacancies at the CDC, the pace of guidance updates to state health departments, and communication with school districts facing local outbreaks. Some lawmakers argued that mixed messaging from federal officials about routine immunizations has compounded existing vaccine hesitancy, though they stopped short of directly tying specific comments by Kennedy to the current spike in cases.
It is worth noting that the connection between Kennedy’s leadership and rising measles cases is asserted by his political opponents but not established by any published epidemiological analysis. Measles outbreaks are driven by gaps in vaccination coverage, global travel patterns, and local public health capacity, and those structural factors have been building over several years. Decisions about messaging, resource allocation, and international coordination at HHS can influence how effectively the system responds, but attributing the 2026 surge to a single official requires evidence that has not yet been presented publicly.
Where the outbreak stands as of May 2026
The precise 2026 case count shifts weekly, depending on reporting lags between state health departments and federal tallies. The CDC’s national page aggregates state reports but does not always reflect the most recent additions in real time. What is clear from the available data is the trajectory: cases are accumulating faster than at any comparable point in recent years, outbreaks are active in geographically dispersed states, and the international community is watching closely.
Updated vaccination coverage data for 2026 has not been released. Whether immunization rates have continued to fall, stabilized, or improved since the declines documented in 2025 cannot be confirmed from available federal data. State-level reports suggest some outbreaks are concentrated in communities with historically lower vaccination uptake, but without granular, current immunization figures, the relative contribution of these clusters to the national picture remains difficult to assess.
Congress is pressing for accountability. International bodies are flagging the U.S. as a concern. And the country’s measles elimination status, a public health achievement a quarter-century in the making, hangs on decisions that have yet to be made or, in some cases, explained.
