"He's going to help make America healthy again," Trump said in his victory speech on November 6.

"He wants to do some things, and we're going to let him get to it," he said.

On X and interviews in recent weeks, Kennedy has indicated his priorities include addressing what he calls the "chronic disease epidemic" of conditions including obesity, diabetes and autism, and reducing chemicals in food.
