The 79-year-old president had just finished his 40-minute speech in Greensboro, North Carolina, when he turned to the right and held out his hand, even though he was alone on stage. Some of his political opponents, including Republican Sen. Ted Cruz, seized Biden’s latest blunder, using it to challenge his knowledge. Footage from the moment, which was shared by millions on social media, showed the blundered President turning to his right, before appearing to say something in the empty space while imitating a handshake. Biden then turned to his audience, looking disoriented, as assistants and university guests applauded his speech.
