US President Joe Biden said on social media that I don't know what's in these stimulants, but I'm feeling excited, try it yourself. Biden also matched a photo of him holding a bottle of "energy drink", which read "Stop messing around, this is water". Ahead of the general election debate, ABC coverage, Trump's previous rally in Philadelphia continued to claim that if Biden's debate on Thursday night was good, it would be because he took performance-enhancing drugs.
