A U.S. District Court in California court ruled that 0.7 milligrams per liter of fluoride in drinking water poses an unreasonable risk to health.

The city will be seeking a formal opinion from the state on its stance before deciding whether to remove fluoride from its drinking water permanently.

The Washington Post and other media noted that medical organizations responded by calling Kennedy’s assertions unfounded at the levels of fluoridation used in drinking water. But many of them have also noted that in an NBC interview, Trump said possible action against fluoridation of water “sounds OK to me ... You know, it’s possible.”
