Should Biden take a cognitive exam? Democrat Warnock: "I'm not a doctor. It's not something I've even thought about. I'll tell you, Trump is a sick person. He lies every 90 secs. I don't know anybody like that..."
Biden's Spox says "Biden is sharper than ever" and when asked "Should voters know about cognitive ability of candidates?" she says "I don't even know what that question means."
