Dr. Jennifer Layden was the Director of the Office of Public Health Data, Surveillance and Technology at the Centers for Disease Control and Prevention for five years until this week, when she became one of four senior CDC officials to resign amid budget cuts and increased political pressure from President Trump and Health and Human Services Secretary Robert F. Kennedy Jr. “Public health should be bipartisan,” Layden tells Ali Velshi, explaining that budget cuts made it “challenging to do my work.” Many don’t realize how dangerous this undermining of our public health agencies could be since Layden notes that “the work of public health often goes unnoticed until there is a major outbreak.”
