We bring on our colleague Sarah Owermohle to discuss the White House's sudden move to withdraw the nomination of Dave Weldon as its pick to run the CDC just hours before Weldon's confirmation hearing. It's also the five-year anniversary of the Covid-19 pandemic. We chat with Princeton political scientist Frances Lee about a new book she co-authored that offers an unflinching assessment of the U.S. policy responses to the pandemic and raises some provocative questions about what went wrong.
