ST. PAUL, Minn. – President-elect Biden has it right to ask Americans to commit voluntarily to 100 days of mask-wearing, said Governor Tim Walz. The governor called the proposed national mask mandate “the right thing to do.” Walz said 100 days “fits pretty well” with the timeline for a great number of people to be vaccinated against the coronavirus. By then, he said, “we would have a good handle on this.”
