Yo? MAGA morons?
This is just another egregious Trump lie. NO ONE has challenged him on it. He knows that he can spew absolute bullshit and because people are numb to it, he can get away with it.
And somehow, this has pivoted to a "discussion" of whether Biden should take a cognitive test. It's an opportunity for him, though! He should just say, "I'll take the test if you take the exact same test, administered by the same exact doctors, on the same day." Trump would fold his hand.
