NEW: Clinton's general election opponent Donald Trump attacked the former secretary of state -- and she responded
President Barack Obama used a web video to endorse presumptive Democratic presidential nominee Hillary Clinton
President Barack Obama endorsed presumptive Democratic presidential nominee Hillary Clinton in a web video Thursday.
“I don’t think there’s ever been someone so qualified to hold this office,” Obama said in the video.
“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 continued. “I am fired up. And I can’t wait to get out there and campaign with Hillary.”
Obama will campaign with Clinton next week in Green Bay, Wisconsin.
Clinton, Trump battle on Twitter: ‘Delete your account’
“It’s probably the first of many campaign events between now and November,” White House Press Secretary Josh Earnest said, adding that no more campaign events are scheduled yet. Earnest said Obama recorded his video Tuesday.
His endorsement made note of the historic nature of Clinton’s being the first female presidential nominee of a major political party. Obama’s endorsement brings full circle a relationship that began when the two were rivals in the hard-fought 2008 Democratic nominating contest.
Clinton thanked Obama for his endorsement in a tweet posted to her account Thursday.
“Honored to have you with me, @POTUS. I’m fired up and ready to go!” she wrote, signing it with ‘-H’ to indicate the tweet was from the former secretary of state personally.
Clinton also thanked Obama for the endorsement in an interview with Bloomberg Politics, timed to be made public when the White House released 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 said. “It’s just such a treat because over the years of knowing each other, we’ve gone from fierce competitors to true friends.”
Obama was not the only high profile Democratic endorsement Clinton secured Thursday. Vice President Joe Biden endorsed Clinton at an event in Washington, and Massachusetts Sen. Elizabeth Warren endorsed Clinton as well. She delivered a blistering critique of Donald Trump on Thursday at a speech in Washington, continuing her recent role as antagonist to the presumptive Republican presidential nominee.
Warren, a liberal stalwart known for championing issues related to economic inequality, has been one of the few Democratic senators to withhold a formal presidential endorsement.
Clinton’s general election rival, presumptive Republican nominee Donald Trump, cast Obama’s endorsement as motivated by a president who wants to see his policies continued.

Clinton’s comeback: “Delete your account.”
Obama’s endorsement signals an end to the Democratic primary battle between Clinton and Vermont Sen. Bernie Sanders, who has vowed to fight on through next week’s Washington, D.C., primary, but on Thursday didn’t repeat his previous claims that he will fight on through the party’s convention next month in Philadelphia.
Obama tapped Clinton as his first-term secretary of state – linking the two forever in history on decisions like the U.S. raid to kill Osama bin Laden and the military intervention in Libya.
The support came just hours after Obama met with Sanders at the White House.
A senior Sanders aide said the Obama endorsement “was expected” and described the senator’s meeting with the President Thursday as “very good” and “positive.”
“We have run a hard campaign and will compete in the District of Columbia primary, and are proud of what Senator Sanders accomplished,” the source said.
Earnest said Sanders wasn’t surprised by Obama’s move, and praised the Vermont senator for engaging young voters and independents in the primary process.

He wouldn’t nudge Sanders to leave the race. “Sen. Sanders has more than earned the right to make his own decisions on his own time frame,” he said.
The Sanders aide also described the discussions so far between their campaign and Clinton’s as “positive.”
“There are a lot of discussions going on right now and there will be discussions with the Clinton campaign about how to ensure Senator Sanders goals for a progressive agenda are addressed,” the source said.
Late Thursday afternoon, Sanders met with Biden.
Beyond supporting his former secretary of state, Obama has many incentives to see Democrats maintain the White House and reclaim the Senate in the fall: Republicans have vowed to unwind his signature accomplishments, including his landmark health care law, his Iran nuclear deal and his renewal of diplomatic and economic ties between the United States and Cuba.
The President has also raised money for Democrats – including a $10,000-and-up event in Manhattan on Wednesday.
