Washington Post columnist Paul Waldman knocked comedian Jon Stewart for making an impassioned argument in favor of the Wuhan lab-leak theory during his Monday night appearance on “The Late Show.”

Stewart shocked Stephen Colbert’s audience when he suggested it isn’t farfetched to believe that the coronavirus pandemic originated from a Chinese coronavirus lab, comparing it to an “outbreak of chocolaty goodness near Hershey, Pennsylvania.”

“Maybe a steam shovel mated with a cocoa bean… or it’s the f—in chocolate factory!” Stewart exclaimed.

That didn’t sit well with Waldman, who penned a piece on Tuesday titled, “Jon Stewart’s rant is a reminder: Don’t rely on celebrities for covid-19 theories.

“It seems like a long time ago now, but Jon Stewart used to be an immensely important figure sitting at the place where politics and pop culture meet,” Waldman began his op-ed about the former “Daily Show” host. “But these days, he’s retired and only emerges from time to time, and because he always delighted more in skewering Republicans, it was a bit shocking to see him go on an extended rant on ‘The Late Show with Stephen Colbert’ about the coronavirus lab-leak theory.”
