Vice President Joe Biden 'Confident' Hillary Clinton Will Be Democratic Nominee

— -- Vice President Joe Biden today predicted that Hillary Clinton will be his party's presidential nominee, even though the Democratic primary is still underway.

“I feel confident that Hillary will be the nominee, and I feel confident she’ll be the next president,” Biden said in an exclusive interview with “Good Morning America” co-anchor Robin Roberts.

The vice president’s comments came during an interview with Roberts about his “Cancer MoonShot” initiative. President Obama earlier this year announced Biden would lead a "moonshot" endeavor to cure cancer, a disease that claimed the life of his son Beau.

Biden, who decided against a 2016 run of his own, has refrained from endorsing Clinton or her Democratic opponent, Sen. Bernie Sanders, in this election, but his statement is the most direct acknowledgement from inside the White House that Clinton will clinch the nomination.

In an interview with Mic in April, the vice president indicated he would “like to see a woman elected” president. But he has also shown some favor for Sanders’ campaign style and messaging.

“I like the idea of saying, ‘We can do much more,’ because we can,” Biden said in an interview with the New York Times last month.
