Robert F. Kennedy Jr. is the 26th Secretary of the US Department of Health and Human Services (HHS).[5] He was sworn in a year ago promising that changes in federal health policy would restore confidence in public health agencies.[1] More than 750 former and current HHS employees sent a letter asking him to stop spreading inaccurate health information.[2] This letter came after the shooting at CDC headquarters in Atlanta.[2] Kennedy plans to revoke the 16-member Preventive Services Task Force, which recommends free preventive measures for insurance companies under the Affordable Care Act.[3] About 100 million people use these services, including cancer screenings.[3] He has already fired all 17 members of the CDC's advisory panel on vaccination guidelines and replaced them with his own nominees.[3] The American Medical Association expressed deep concern and urged him to retain the original members.[3]
