President Barack Obama endorsed fellow Democrat Hillary Clinton for president because he wants to see at least four more years of an executive instituting and continuing his policies, Republican nominee Donald Trump charged in a tweet.
"Obama just endorsed Crooked Hillary," Trump tweeted. "He wants four more years of Obama — but nobody else does!"
In a three-minute-long video announcing his endorsement, Obama congratulated Clinton on sealing the Democratic nomination and said she's the clear choice of a majority of primary voters.
"I have seen her judgment, I've seen her toughness, I've seen her commitment to our values up close," the president said.
The president said he'll spend some of his remaining time in office stumping for his fellow Democrat, who opposed him in the 2008 Democratic primary before he was elected president.
"I want those of you who have been with me since the beginning of this incredible journey to be the first to know that I'm with her," Obama said. "I am fired up. And I can't wait to get out there and campaign with Hillary."
Clinton thanked Obama for his endorsement in an interview with Bloomberg, which was conducted ahead of time and released at the same time as Obama's endorsement video.
"It just means so much to have a strong, substantive endorsement from the President. Obviously, I value his opinion a great deal personally," Clinton told Bloomberg. "It's just such a treat because, over the years of knowing each other, we've gone from fierce competitors to true friends."
Clinton's next challenge will be courting supporters of Vermont Sen. Bernie Sanders, who has said he will not suspend his campaign and intends to contest the Democratic convention.
