American University students were all a-Twitter this weekend as word made its way around campus that Mike Tyson was attending Saturday’s College of Arts & Sciences graduation. Tyson was there to see his daughter graduate. The boxing legend sat with his ex-brother-in-law, former Republican National Committee Chairman Michael Steele, at the ceremony. We’re told Tyson later took his daughter out for a graduation dinner at the California Pizza Kitchen at Montgomery Mall in Bethesda.
