Philip D. Zelikow led the congressionally chartered inquiry into the terrorist attacks on Sept. 11, 2001. Now, he is laying the groundwork for a national commission to investigate the COVID-19 pandemic and propose forward-looking policy recommendations. The attorney, diplomat and University of Virginia professor joins Washington Post deputy editorial page editor Karen Tumulty to discuss the Covid Commission Planning Group. This group is planning a large investigative effort along multiple lines of inquiry, including the origins of the pandemic, failures of pandemic preparedness and response, the impact of COVID-19 on at-risk communities and the development and distribution of vaccines and therapeutics.
