In a speech at the University of Pennsylvania's Penn Biden Center, former Vice President Joe Biden unloaded on Donald Trump's "naked nationalism" — but didn't even mention the president's name.

"The worst thing in the world we can have is this new naked nationalism, America first," Biden said during the speech, as quoted by CNN's Arlette Saenz. "I believe making America first in the way we're doing it will make America last."
