Fallout from the closure of Mount Ida College continued this week with new revelations of personal and business ties between the college president and a benefactor who loaned the college money to try to keep it operating.  The disclosures, outlined in an article by The Boston Globe on Sunday, suggested  to some experts a conflict of interest between Barry Brown, president of the Newton, Mass., institution, and Rosalie K. Stahl, a 98-year-old New York City real estate investor and longtime personal client of Brown.  Brown, is a trustee of Stahl’s personal trust, according to the article.
