Sen. Bernie Sanders, the runner- up for the Democratic presidential nomination, vowed on Sunday to "campaign vigorously" for the winner, Hillary Clinton.

"I'm going to do a couple of things," the Vermont independent said on CBS' ' "Face the Nation." "No. 1, I intend to campaign vigorously to make the case that on issue after issue Clinton is far and away the superior candidate. No. 2, to stay focused on the real issues impacting the American people."


Pressed by CBS host John Dickerson on whether his supporters would vote for Clinton, Sanders ticked off a series of issues popular among progressives, including overturning the Supreme Court's Citizens United ruling, raising taxes on the wealthy and increasing the minimum wage.

Clinton's positions on those issues, Sanders said, clearly show she is the best candidate.

"So I would ask ... my supporters to get away from the personality conflicts that media tries to bring forward and focus on the real issues impacting the American people," Sanders said. "And when you do that, I think the choice is pretty clear, and that is that Hillary Clinton is far and away the superior candidate."

By contrast, Sanders slammed the campaign of Republican rival Donald Trump for dividing the nation.

"That is not what our country needs," Sanders said. "In these stressful times, we ought to bring our people together, not divide us up, which is what Trump is trying to do."
