Joe Biden leads Donald Trump by nine points nationally in the latest polling from Reuters/Ipsos, as the president’s “law and order” response to civil unrest in the wake of George Floyd’s killing fails to win support from prospective voters.
The ex-veep has meanwhile laughed off Trump’s accusation on Fox and Friends that he is using performance-enhancing drugs to boost his appearances on the campaign trail as “foolish”, saying he is keen to debate his antagonist.
While the president called on the Biden-Harris ticket to stop their reckless anti-vaccine theories that would put lives at risk, Mr Biden accused the Trump administration of speeding up the coronavirus vaccine for political purposes.
He said he trusts vaccines and scientists, but he doesn't trust the president and neither should the American people.
The candidate made the legal case for a national mask mandate, saying his legal team was looking at an executive order for the country. But if it wasn't legal, he would bring all Republican and Democratic governors to the White House and persuade them with the science to institute the mandate.
He earlier reminded voters that he is “not currently president” after Mr Trump blamed Democrats for not introducing a national mandate on mask-wearing amid the coronavirus pandemic.
