"Intelligence agencies," he added, "spent a lot of time and energy infiltrating Chinese research programs, including military programs, and they were trying to protect their assets as far as possible so [they] did not want any investigations into that [Wuhan] laboratory.
"The more scrutiny of the laboratory, especially by the Chinese leadership, the higher the risk. I don't know all the answers, but the bottom line is that this does not smell right."
Redfield said he expects the Trump administration to declassify information pertaining to the outbreak.
"I suspect all the intelligence agencies will — like the CIA — have to reevaluate their analysis on COVID and will be unanimous in their conclusions. I think they'll all come out and say critical analysis of the intelligence data concludes it came from the lab."
