LA County says the average daily COVID case rate and test positivity rate have doubled in the past week. That’s partly due to the highly contagious Delta variant, which is affecting unvaccinated people.

Andy Slavitt is President Biden’s former senior advisor on COVID, and the author of “Preventable: The Inside Story of How Leadership Failures, Politics, and Selfishness Doomed the U.S. Coronavirus Response.” He talks to KCRW about the risks the Delta variant poses, and how political leadership factored into America’s dismal response to the pandemic.
