Face the Nation on the Radio 1/3/21

The long wait -- as a COVID-19 vaccine roll out continues -- but why is it taking so long to get the shots to most Americans? We talk to Operation Warp Speed's chief adviser Moncef Slaoui as well as former FDA Commissioner Scott Gottlieb. We'll hear from Los Angeles Mayor Eric Garcetti about the surge in coronavirus cases in LA. Meanwhile, Republican Senator Asa Hutchinson of Arkansas says nearly 1/4 of the Senate GOP plans to challenge President-Elect Biden's 2020 win. Moderator Margaret Brennan will have all that and more on this week's "Face the Nation."
