2:25 pm: Biden campaign beats Trump for “politicizing” masking for months and “actively deter” issue
A spokesman for former Vice President Joe Biden’s campaign reacted to President Trump’s decision to wear a mask during his visit to Walter Reed Medical Center on Saturday, slamming him for months “ignoring the advice of medical experts” and “politicizing” masking.
“Donald Trump 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. Instead of taking responsibility and leading, he wasted four months on Americans has made sacrifices by stopping divisions and actively discouraging people from taking a very basic step to protect each other, “campaign spokesman Andrew Bates wrote in a statement released Saturday night.
“However, 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 continued.
Many Biden employees have taken to social media on Saturday to point out that Biden has been wearing a mask for months, and that President Trump mocked him for doing so during a Memorial Day visit to a war memorial.
“Our adult son president remembered not to spread or catch an infectious respiratory disease today. Is this leadership ?? “The Biden campaign’s Digital Director Rob Flaherty joked.
