Former President Donald Trump expressed initial support for a proposal floated by Robert F. Kennedy Jr. earlier this weekend when he vowed on Day 1 of a possible second Trump administration to “advise all U.S​. water systems to remove fluoride from public water.”

Asked by NBC News’s Dasha Burns on Sunday whether he would be “on board” with such a proposal, Trump said, “Well, I haven’t talked to him about it yet, but it sounds OK to me. You know it’s possible.”
