Citation From the February 18, 2020, edition of Fox News' Tucker Carlson Tonight

TUCKER CARLSON (HOST): Some people, and this includes a few actual experts on the subject, are considering another possibility -- that the coronavirus was made in a lab in Wuhan. You’ve probably seen that on the internet. Is that true? How plausible is this theory? Worth getting to the bottom of.

…

CARLSON: Is there any evidence as of tonight that this virus originated in a lab?

BILL GERTZ (THE WASHINGTON TIMES): Well, I don’t know. We don’t know that they were. We know that -- here’s another fact. The Wuhan Institute of Virology has the only P4 lab, that is for pathogen 4 -- it’s the most secure lab you can have. There’s only one in China that’s declared, and it’s in Wuhan, and it’s like, 20 miles from this market. That’s a fact.

…

The White House just last week ordered the National Academy of Sciences to conduct a study. They say hey look, we’ve got to find out the origins of this, so they want to know what the origin is too.

CARLSON: So, I mean, I think the headline in this conversation -- which I appreciate, I appreciate your sober analysis -- is that we don’t actually know and anyone pretending that he or she knows is lying.
