Trump mocks Biden by appearing clueless on stage

Ex-US president Donald Trump has drawn applause from his supporters when he shuffled around the stage pretending he was struggling to find the exit, suggesting he may revive a theme from his 2020 campaign when he portrayed President Joe Biden as senile and lacking energy and acuity.

"I'm running for president? Where? Where am I going? Where the hell am I going? I want to get out. Oh, no. Over there. Over there," Trump said.
