President-elect Donald Trump has picked Robert F. Kennedy Jr. to be his next secretary of the Department of Health and Human Services, a choice that would add to Trump’s list of provocative picks whose confirmation processes will test the loyalty of Senate Republicans, writes CNN.

Trump announced the selection, confirming CNN’s earlier reporting, saying he was thrilled to share the pick.

“The Safety and Health of all Americans is the most important role of any Administration, and HHS will play a big role in helping ensure that everybody will be protected from harmful chemicals, pollutants, pesticides, pharmaceutical products, and food additives that have contributed to the overwhelming Health Crisis in this Country. Mr. Kennedy will restore these Agencies to the traditions of Gold Standard Scientific Research, and beacons of Transparency, to end the Chronic Disease epidemic, and to Make America Great and Healthy Again!” - Trump said in a post on X.

Kennedy, who accepted the offer Thursday, has been one of the nation’s most prominent anti-vaccine conspiracy theorists for years and has frequently spread false conspiracy theories about the safety and efficacy of vaccines. He has been in Palm Beach, Florida, for several days following the election.

In a statement Thursday, Kennedy emphasized the importance of ridding the department of “corruption” and vowed to “provide Americans with transparency” so they can make individual health decisions.

“I look forward to working with the more than 80,000 employees at HHS to free the agencies from the smothering cloud of corporate capture so they can pursue their mission to make Americans once again the healthiest people on Earth”, Kennedy said.
