Vice President Joe Biden is telling Air Force Academy graduates their country still needs them because they can "do it all."
Biden spoke to about 1,000 graduating cadets at the Air Force Academy in Colorado Springs on Wednesday.
Biden says the nation faces daunting challenges -- not just enemy states and terrorism, but global warming and improving health care and education.
Biden says the graduates should "think beyond the theater of battle."
The vice president also poked fun at President Barack Obama, who's known for relying on teleprompters for his speeches.
When Biden's teleprompter failed, he joked he'd have to tell the president about it, saying, "What will he do then?"
