Colorado Gov. John Hickenlooper on Wednesday confirmed meeting with presumptive Democratic nominee Hillary Clinton “briefly” in Denver last week to discuss the possibility of joining the ticket as her running mate.

“If you look at the challenges that this country and the world faces right now, if you’re someone who’s asked, that you’re one of the people that can really make a difference and your country needs you, of course you take it seriously,” Hickenlooper told Bloomberg TV’s David Gura.
