Michelle Obama didn’t feel “welcome” at Princeton either - probably because her SAT score would not have even gotten her into U. Of Illinois were she White.
Having read part of Michelle Obama’s senior paper I don’t think she would have been admitted to the University of Illinois in Champaign-Urbana. I don’t know much about their Chicago campus but the main campus is a competitive school.
I’m sure the DEI “officers” and “advisors” are the ones who feel most welcome.
