[US President Biden "responds" to doping allegations] Golden Finance reported that US President Biden said on social media, "I don't know what's in these stimulants, but I feel excited, you can try it yourself." Biden also posted a photo of him holding a bottle of "functional drink", with the words "Stop it, it's just water" written on the bottle. Before the election debate, ABC News reported that Trump continued to claim at a rally in Philadelphia that if Biden performed well in the debate on Thursday night, it would be because he took performance-enhancing drugs.
