COVID-19 vaccine should not be mandatory: Biden

"No, I don't think it should be mandatory. I wouldn't demand that it be mandatory, but I will do everything in my power, just like I don't think masks have to be made mandatory nationwide... I will do everything in my power as the President of the United States to encourage people to do the right thing," Biden said.

He added that in his inaugural speech he will ask Americans to commit for 100 days to wearing a mask, saying that wearing masks is 'not a political issue, it's become one.'
