This past January, just a few days after the inauguration of President Joe Biden, six of the doctors responsible for the previous administration's Covid-19 response agreed to sit down -- in strict confidence -- and talk with CNN's Dr. Sanjay Gupta about the events of the past year. During one of those conversations, Dr. Robert Redfield, director of the Centers for Disease Control under former President Donald Trump, revealed that he believed the Covid-19 coronavirus originated in a lab in China. Watch, "COVID WAR: The Pandemic Doctors Speak Out," at 9 p.m. Sunday, March 28, only on CNN.
