U.S. Health Secretary Robert F. Kennedy Jr. is appearing before a congressional committee Thursday, where he's expected to face questions about turmoil at federal health agencies. Toward the end of his opening remarks, Kennedy said he wanted to address “the recent shakeups at CDC,” personnel changes he called “absolutely necessary adjustments to restore the agency to its role as the world’s gold standard.” Kennedy went on to describe COVID-19-era recommendations and policies he said were implemented “with no science and heightened economic inequality,” like school closures. Last week, the Trump administration fired the agency’s director Susan Monarez. Several top CDC leaders resigned in protest, leaving the agency in turmoil.
