If I could think of one word to describe Joe Biden, "cognitive" would not be it. The most popular president ever gets confused whenever he's in front of a microphone. He starts telling stories that may or may not have happened. Whether or not he's knowingly spinning a tall tale or he thinks these things actually happened to him, to quote Biden himself, "We choose truth over facts." Our president wanted to look like a big shot in front of the Los Angeles Dodgers. He had a tale of that one time he hit a baseball. Whether you think he's lying, stretching the truth, or really thinks this story happened depends on how charitable you choose to be.
I choose to be as charitable as the mainstream media would be if this were Donald Trump saying it.
