From the March 30, 2020, edition of Fox News' Tucker Carlson Tonight

DR. MARC SIEGEL (FOX NEWS MEDICAL CONTRIBUTOR): I also want to give a shout out to somebody called Tucker Carlson, who because of your attention to hydroxychloroquine, night after night talking to frontline people about this drug, insisting that it be taken seriously, I believe our focus on this drug has led directly to FDA emergency approval, which may save many lives, Tucker.

TUCKER CARLSON (HOST): So how do -- thank you. I mean, obviously not my lane, but it does seem promising. Is it turning out to be? Are doctors using it effectively to treat this disease?
