Outspoken host Tucker Carlson outlined Monday how the possibility of a lab leak causing the coronavirus outbreak was dismissed and lied about for over a year by those directing the pandemic response, and is only now emerging as a serious prospect because of the persistence of those who refused to be silenced.

"Pretty much every sane person acknowledges at this point that the government of China likely caused the single worst man-made disaster in human history," Carlson noted, citing the release of a US intelligence document acknowledging that workers at the Wuhan Institute of Virology were hospitalised in November 2019.

The host noted that Anthony Fauci has admitted that he had no idea about the revelations, even though they were first brought to light in January, and rumours about the workers getting sick have been known for over a year.

"Fauci's own employers, the U.S. government, publicly released compelling evidence that the virus that he has devoted his life to fighting, did not come from food, but instead escaped from the very bio lab that Tony Fauci has sent American tax dollars to fund," Carlson announced.

"Yet somehow Tony Fauci didn't know this… Can we really believe that? No, of course, we can't," Carlson continued, adding "right around the time those Chinese researchers became the world's first COVID patients, the government of Thailand contacted the CDC and Tony Fauci's office to say its intelligence service had picked up 'biological anomalies' around the lab in Wuhan. In other words, there had been a leak."

Carlson continued "several other allied foreign governments, including the governments of France and Australia, have gathered evidence showing the virus escaped from a Chinese lab. Yet Tony Fauci, who runs the whole thing, didn't know any of this? Come on. Of course he did."
