Weekend Roundup: 01/29

On this episode of the "CBS News Weekend Roundup," the world passes another grim milestone, as coronavirus cases rise in nearly 40 nations. CBS News Correspondent Allison Keyes speaks with CBS News Chief Medical Correspondent Dr. Jon LaPook about why it is so hard to get vaccines as the new head of the CDC says shots should be available to everyone in the nation by the end of the summer. In this week's Unifying America edition of the Kaleidoscope, we take a look at four racial equity executive orders signed this week by President Biden. Allison asks Howard University's chair of Afro-American studies, Dr. Greg Garr, what he thinks of the orders and whether they will bring changes. Plus, we remember the life and career of award-winning, iconic actress Cicely Tyson, who died this week at the age of 96.
