US President Biden stated on social media that he doesn't know what's in these stimulants, but he feels excited and suggested others try it out. Biden also posted a photo of himself holding a bottle of "functional beverage," which had the words "don't worry, it's just water" written on it. Prior to the presidential debate, ABC News reported that Trump had previously claimed at a rally in Philadelphia that if Biden performs well on Thursday night, it will be because he took performance-enhancing drugs.
