Democratic Presidential candidate Joe Biden says on Monday that US President Donald Trump is “responsible” for catching the COVID-19.

Biden gives such a statement looking at Trump’s decision on not wearing masks at the White House after a hospital stay and avoid social distancing.

Biden was questioned if he agrees with a recent poll says 65 percent of Americans think the president bears some responsibility for contracting this virus, to which he replied, "Look, anybody who contracts the virus by essentially saying masks don't matter, social distancing doesn't matter, I think is is is responsible," Biden told an NBC town hall in Miami, Florida.

"I would hope that the president, having gone through what he went through and I'm glad he seems to be coming along pretty well, would communicate the right lesson to the American people. Mask's matter," he added.

While, Trump told Americans "to get out there" and not fear COVID-19 as he returned to the White House on Monday and removed his white surgical mask to pose for pictures.
