The two men sat
relatively near each other at the event in Philadelphia, where
the Trump family gathered to watch the real estate tycoon's
daughter, Tiffany, graduate from the Ivy League school. Biden
came to support granddaughter Naomi.
Tiffany Trump, 22, is the daughter of Trump and his ex-wife
Marla Maples. Naomi Biden is named after the vice president's
one-year-old daughter, who died in a 1972 car accident along
with the girl's mother, Biden's first wife.
Donald Trump, who earlier this month effectively secured the
Republican nomination for the Nov. 8 presidential election, also
attended the University of Pennsylvania, graduating from its
Wharton business school.
Biden, who is not running in the 2016 election, has been a
bitter critic of Trump's policies and campaign tactics, calling
the Republican front-runner's remark that Mexico was sending
rapists and other criminals across the border a "sick message."
