A spokesman for presumptive Democratic presidential contender Joe Biden’s campaign has criticized US President Donald Trump, saying that he "spent months ignoring the advice of medical experts and politicizing wearing a mask, one of the most important things we can do to prevent the spread of the virus," ABC News reports.
The spokesman also noted that Biden has been wearing a mask for months already: "By contrast, Joe Biden has led by example from the start and as President will make decisions informed by science to protect the American people and defeat the virus,” he said.
Many other Biden staffers pointed out that President Trump mocked Biden for wearing a face mask during a Memorial Day visit to a war memorial.
