"My predecessor -- to be very blunt about it -- did not do his job in getting ready for the massive challenge of vaccinating hundreds of millions of Americans. He didn't order enough vaccines. He didn't mobilize enough people to administer the shots. He didn't set up federal vaccine centers where eligible people could go and get their shots.," said the President.

We're going to face setbacks along the way and I promise you when we do I'll just own up to it and say what they are."
