The president of Norwich University said he is departing the military school after more than three years on the job.  Mark Anarumo told VTDigger on Friday that he was leaving by “mutual” decision. Provost and Dean of the Faculty Karen Gaines will serve as acting president, according to Anarumo and an email that Gaines sent to members of the school community, which was obtained by VTDigger and confirmed by a person who works at the school.
