I faced like many of you defining moment, walk away from public life or stay. I chose to stay.

All of those who have been knocked down, counted out, left behind, this is your campaign.

It's a story of America today. It's the story of America of the future.

The President announced that his administration is ready to deploy 125 million masks as well as CDC teams to help schools meet safety standards.
