Former U.S. State Department deputy Randall Tobias won't deliver the commencement address for Indiana University School of Law-Indianapolis to avoid being a distraction following his resignation last week.

Tobias resigned as director of U.S. Foreign Assistance and US Agency for International Development Administrator on Friday, citing 'personal' reasons, following the disclosure that he had been a client of the so-called "D.C. madam" escort service. Tobias told ABC News he received massages from the company's workers at his house, but not sex.

IUPUI interim dean Susanah Mead told students in an e-mail that Tobias "called me (Wednesday) to discuss his thoughts about whether his participation could be a distraction, given current events."

Mead said Tobias "indicated that he did not want anything to detract from this very important day for you and your families and therefore he has decided that it would be best if he did not participate in the day's activities."
