The University of Pennsylvania is Donald Trump's alma mater
Vice President Biden was also welcomed on stage to greet and hug granddaughter Naomi
Donald Trump on Sunday occupied an unusual spot at a heavily-attended event – the audience.
Instead of appearing on stage and leading a raucous campaign rally, the presumptive Republican nominee sat among the crowd alongside his family at daughter Tiffany Trump’s graduation ceremony from University of Pennsylvania.
The University of Pennsylvania is Trump’s alma mater; he graduated in 1968 from the business program at The Wharton School.
Trump wasn’t the only high-profile guest at the Ivy League graduation ceremony – Vice President Joe Biden was also there for his granddaughter Naomi Biden.
The two families were seated a section apart in the stadium and both received applause after entering.
Biden was also welcomed on stage to greet and hug Naomi as her name was called.
