Trump approves of RFK Jr.'s plan to remove fluoride from public water.

• Donald Trump, the former president, expressed his agreement with Robert F. Kennedy Jr.'s plan to eliminate fluoride from American water sources.
• Kennedy, set to assume a health policy role in a prospective Trump administration, penned, "The Trump White House will instruct all U.S. water systems to exclude fluoride from public water."
• The Centers for Disease Control and Prevention confirm that the safety and benefits of fluoride have been thoroughly examined and supported by numerous scientific and public health organizations.

On Sunday, former president Donald Trump expressed his support for Robert F. Kennedy Jr.'s plan to remove fluoride from the U.S. water supply, despite the advice of public health agencies.

In an interview with NBC News' Dasha Burns, Trump stated that he hadn't discussed Kennedy's proposition with him yet, but it sounded acceptable to him. He added that it was possible.

On January 20, the Trump administration will advise all U.S. water systems to remove fluoride from public water.

Trump stated that Kennedy would play a significant part in shaping public health policy in any Trump administration.

According to the Centers for Disease Control and Prevention, fluoride is naturally present in almost all water sources and is added to public water to prevent cavities.

The CDC website post states that the safety and benefits of fluoride have been thoroughly examined and documented by numerous scientific and public health organizations.

Community water fluoridation, which involves adding fluoride to water, has been proven safe and effective through 70 years of research, according to the American Dental Association.

The Trump campaign did not promptly react to CNBC's inquiry about the fluoride comment.

Kennedy is a well-known vaccine skeptic who has helped spread false conspiracy theories about public health. Trump left the door open to banning certain vaccines if he were president and Kennedy was in his administration when asked by NBC News.

Trump stated that he would consult with others and make a decision, but he considered the individual to be highly skilled and possessing firm convictions.

The Trump campaign faces a challenge in its final days: staying on message about public health, as Trump's doubts about fluoride and water fluoridation raise questions for voters.

Over the weekend, comedian Tony Hinchcliffe made a derogatory comment about Puerto Rico, calling it a "floating island of garbage." The Trump campaign subsequently issued a statement distancing itself from the remark.

For several days, comments about the news cycle dominated the headlines, until President Joe Biden made a statement that he did not intend to call Trump supporters "garbage."

This week, Republicans contend that voters are disregarding the contentious remarks made by Trump and his allies and are instead concentrating on the major concerns in the election.

On CNN's "State of the Union" Sunday, Sen. Tim Scott, R-S.C., stated that voters in Michigan, Ohio, Wisconsin, Pennsylvania, Georgia, and North Carolina are all discussing crime and unemployment.

"The conversation is centered on the border, the 70,000 American lives lost to fentanyl, but not on fluoride."
