People ask this as some sort of weird gotcha, but it’s actually not that interesting, nor should it be surprising. After all, the previous administration was filled with habitual liars at every level who kept pushing “alternative facts” over observable reality and shat on the media at every opportunity. As such, everything they claimed was viewed as a likely lie, and rightly so.
New developments have happened as well, though. I believe we recently started hearing about Wuhan lab employees starting to get sick around late 2019 and early 2020. I don’t think we had known that before.
