Palm Beach, Florida - Former presidential candidate Robert F. Kennedy Jr. is making some big campaign promises for Donald Trump, and The Don is on board.

Over the weekend, Kennedy shared a post on X boldly declaring that "on January 20, the Trump White House will advise all US​ water systems to remove fluoride from public water."

"Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease," Kennedy continued.

"President [​Trump] and First Lady [Melania Trump] want to Make America Healthy Again," he added.

The promise comes after Kennedy ran a failed presidential campaign as an Independent, ultimately dropping out and endorsing Trump.

Kennedy, a leading figure in the global anti-vaccine movement, has since become an enthusiastic surrogate for Trump, who has promised him a role in his administration. At a recent rally, Trump told the crowd he will be letting Kennedy go "wild" on health, medicine, and food.

When Trump was asked by NBC News about Kennedy's water proposal on Sunday, he admitted, "I haven't talked to him about it yet, but it sounds OK to me."

When asked if he would consider getting rid of vaccines, Trump said, "I’m going to talk to [Kennedy] and talk to other people, and I'll make a decision, but he's a very talented guy and has strong views."
