USSC Non-Resident Fellow Victoria Cooper talks to ABC Radio's The World Today about President Joe Biden's beleaguered campaign and his gaffes at the NATO Summit press conference, where he referred to Vice President Kamala Harris as "Vice President Trump."

"Moments like this aren't necessarily reflective of the cognitive abilities of the president for example, they're often just a gaffe, but they do become sort of social media memes," she said. "They become these snackable moments that people like to replay."
