"Barack and I are going to support whoever wins the primary, our primary focus is letting the primary process play out," she said. 

Obama added that it's too early to predict who will become the party nominee. 

"It's like trying to figure out who's going to win the World Series on the first seven games, that's where we are right now. It's so early and things will change," she said. 

Obama said she and the former president are watching, supportive and offering advice to candidates who seek it. 

When King asked Obama to share what qualities she believed a president should have, she shot back: "I talked about this in the last campaign but nobody listened." 

"I was like, 'It's a hard job y’all.' Let's be clear, this isn't a joke. It's not a game," she said.

"The leader of the free world with a tweet can start war, can crush an economy, can change the future of our children," Obama added. "It is a real job that requires deep seriousness and focus, somebody who has to have enough understanding of history so that you don't repeat what hasn't worked."
