Trump, Biden at Penn graduation as parent, grandparent

PHILADELPHIA -- Both Republican presidential candidate Donald Trump and Vice President Joe Biden attended a graduation ceremony at the University of Pennsylvania, but not on the stage as politicians - they were in the audience as parent and grandparent.

The Republican presidential candidate's daughter Tiffany Trump and the vice president's granddaughter Naomi Biden are among 1,500 students graduating Sunday from the School of Arts and Sciences.

"It was exciting because in my major, Biden came up on stage for his daughter, who is also in international relations," said Silva Stewart.

Donald Trump graduated from Penn's Wharton School of Business in 1968.

Secret service agents were around Franklin Field, metal detectors were in place, and police dogs were on patrol.

Security lines were long, but moved fast.

"We were told to get here two hours early because of them, but turns out it doesn't seem like we needed to," said Scott Tonn.

Trump and Biden aren't expected to attend Monday's main graduation ceremony for the Ivy League school.
