The man is a liar, among other things. I don't believe that tenure rules protect anyone from the consequences of lying on a job application.
It shouldn't, but tenure is jealously guarded by the rest of the lefty profs, in the event their own shady or questionable pedigrees are ever called into question. What was that famous quote...'The only way to get rid of him is to catch him in bed with a dead girl or a live boy.' And of course, in today's university environment, that only leaves the dead girl clause.
Regardless, it's pretty humorous that this bitter, gnarly old white guy was chosen to lead 'ethnic studies'.
