Joe Biden surprises students after speech at University of Denver

DENVER -- Joe Biden became the first sitting vice president to visit the University of Denver on Thursday, speaking at the annual Korbel dinner.

The dinner raises money for the School of International Studies.

Biden spoke for well over an hour, discussing the importance of leadership in a fast and changing world.

Biden did not engage in politics.

The best view of the vice president on campus was perhaps not by one of the donors, but instead the students who got a surprise visit by him afterward.

The students asked Biden about Iraq and Brexit as well as how he became one of the more popular politicians in America.

"There is only one way to become the most popular politician in America: Announce you are not running for president," Biden said.
