Biden administration seeks last-minute appeal of court loss over fluoride in water

Attorneys for the Biden administration said Friday they would seek to challenge a court loss last year that could pave the way for the Trump administration to ban the use of fluoride in water.

The Biden administration's notice, filed Friday with the federal district court in San Francisco, comes just days ahead of a Jan. 21 deadline for the appeal. 

While last year's ruling did not order the Environmental Protection Agency to ban water fluoridation, opponents say it carved out a "clear legal pathway" giving the federal government authority to force local governments to stop adding the chemical to the water supply.
