"To all those who supported our campaign, I'm humbled by the faith you've placed in us. To all those who did not support us, let me say this. Hear me out as we move forward. Take a measure of me and my heart. If you still disagree so be it. That's democracy. That's America. The right to dissent, peaceably, the guardrails of our republic is perhaps this nation's greatest strength," the president added.

"Yet hear me clearly: disagreement must not lead to disunion. And I pledge this to you, I will be a president for all Americans. All Americans. And I promise you I will fight as hard for those who did not support me as for those who did," he stressed.
