President Obama endorsed Hillary Clinton for president in a video released just after he spent an hour in the Oval Office talking with Bernie Sanders. Sanders appeared smiling in video with Obama, indicating he had made peace with his defeat for the Democratic presidential nomination.

The video endorsement was first released through Clinton's Twitter account Thursday afternoon.

Honored to have you with me, @POTUS. I'm fired up and ready to go! -H

President Obama will travel to Green Bay, Wisconsin, to campaign with Clinton next week, which his White House spokesman said is "only the first of many campaign events between now and November."

As for Donald Trump, Clinton quickly suggested the GOP presumptive presidential nominee quit Twitter after he tweeted "Obama just endorsed Crooked Hillary. He wants four more years of Obama--but nobody else does!"
