Former US president Barack Obama mocked Donald Trump at an election rally for Joe Biden in Florida.  Obama criticised his successor’s response to the coronavirus pandemic, noting that Trump has complained about the news coverage the pandemic has received as the US death toll continues to climb. ‘He’s jealous of Covid’s media coverage,’ Obama said. The former president also criticised Trump for his personal lack of coronavirus safety, saying that he has turned the White House into a ‘hot zone’ in the wake of two coronavirus outbreaks among the president and his senior staff.  ‘Florida, we can’t afford four more years of this,’ Obama added. ‘We cannot afford this kind of incompetence and disinterest.’
