Joe Biden awkwardly stumbles into pole and doesn't shake President Lula's hand

President Joe Biden appeared to wander off the UN stage without shaking hands with Brazil 's Luiz Inácio Lula da Silva at the end of a joint speech, leaving the leader looking visibly irritated. Biden, 80, shared a stage with Lula, 77, in a gaffe-filled presentation about their vision to jointly improve workers' rights in their countries. But their diplomatic meeting got off to a labored start when Biden shuffled into a seven-foot Brazilian flag, leaving it teetering slightly as he approached the podium.
