"I'm not 80 and I'm not that close to 80," Trump said when criticizing President Joe Biden's age. In fact, Trump would be 80 less than half way through his term if he were elected.
Tim O'Brien, who spent massive amounts of time with Trump before writing TrumpNation: The Art of Being the Donald, said in response, "He's always been alarmingly bad at math."
Harris-Walz campaign spokesperson Sarafina Chitika asked, "Does [Trump] know how old he is?"
Attorney Jeffrey Evan Gold chimed in:
"He'll be 80 in a year and a half."
Carl Allen, researcher and analyst of sports and political data, said, "Media on Biden's age: ancient. Big problem Media on Trump's age: not even 80!"
Republican accountability group American Bridge 21st Century said on Sunday, "He's 78 and very desperate."
