‘What’s he doing?’: Donald Trump blasts Joe Biden at fiery rally

Republican presidential nominee Donald Trump has questioned “why” he decided to debate US President Joe Biden. The former US president spoke at a campaign rally in Bozeman, Montana. “What’s he doing now? What’s he doing?” Mr Trump said. “He wanted to debate – if we didn’t have a debate, he’d still be there, can you imagine? Why the hell did I debate him.”
