If you run across claims about Claudine Gay, be very wary; by all appearances this seems to be another wave of racist harassment disguised as criticism, from all of the usual right-wing pundits who Suddenly(tm) care about academic integrity now that it's a Black woman they can point their anger towards

(Like how nobody except said right-wing pundits seem to believe that any plagiarism actually happened, not even the authors in question whose work was supposedly 'plagiarized')

WaPo has an article, I wouldn't exactly call it excellent, but it does at least provide a lot of context for what's going on: https://www.washingtonpost.com/education/2023/12/15/harvard-president-claudine-gay-race-criticism/
