Her friend's statement basically reads "Hell no. I'm not getting involved. I was also underage and drinking alcohol with older boys, one of whom is about to become a very, VERY powerful man."

I'm still looking for a plausible explanation why this very successful and respected professor would put herself and her family through this ordeal if her story wasn't true.
