Kevin Warsh, set to take over as fed chair this week, vowed in his confirmation hearing that he would be independent of the White House. For more than a year, outgoing chair Jerome Powell, himself a Trump pick, has faced relentless criticism and legal targeting by this administration. And this unprecedent pressure campaign is the subject of a new "Frontline" documentary, "The President vs. The Fed." The doc's director, James Jacoby, joins the show from New York. 

Also on today's show: Dr. Paul Offit, Director of the Vaccine Education Center, Children's Hospital of Philadelphia; Tyler Pager, White House Correspondent, The New York Times
