His said his grandparents from Kansas didn't value braggarts or people looking for short cuts. They believed in people helping each other out. Their values, he said, "weren’t reserved for one race; they could be passed down to a half-Kenyan grandson, or a half-Asian granddaughter.”

UPDATE: 6:20 p.m. EDT -- The White House released excerpts of President Barack Obama's Democratic National Convention speech. It reads: 

"The America I know is full of courage, and optimism, and ingenuity. The America I know is decent and generous. Sure, we have real anxieties – about paying the bills, protecting our kids, caring for a sick parent. We get frustrated with political gridlock, worry about racial divisions; are shocked and saddened by the madness of Orlando or Nice. There are pockets of America that never recovered from factory closures; men who took pride in hard work and providing for their families who now feel forgotten. Parents who wonder whether their kids will have the same opportunities we have. All that is real; we’re challenged to do better; to be better. But as I’ve traveled this country, through all fifty states; as I’ve rejoiced with you and mourned with you, what I’ve also seen, more than anything, is what is right with America. I see people working hard and starting businesses; people teaching kids and serving our country. I see a younger generation full of energy and new ideas, unconstrained by what is, and ready to seize what ought to be.

You know, nothing truly prepares you for the demands of the Oval Office. Until you’ve sat at that desk, you don’t know what it’s like to manage a global crisis or send young people to war. But Hillary’s been in the room; she’s been part of those decisions. She knows what’s at stake in the decisions our government makes for the working family, the senior citizen, the small business owner, the soldier, and the veteran. Even in the middle of crisis, she listens to people, and keeps her cool, and treats everybody with respect. And no matter how daunting the odds; no matter how much people try to knock her down, she never, ever quits. That’s the Hillary I know. That’s the Hillary I’ve come to admire. And that’s why I can say with confidence there has never been a man or a woman more qualified than Hillary Clinton to serve as President of the United States of America."

Original story:

President Barack Obama came out of nowhere to block Hillary Clinton's presidential ambitions during the 2008 Democratic primary. Eight years later, he is expected to open wide the door to the White House for her in a rousing endorsement speech Wednesday night at the Democratic National Convention. 

Obama will headline the event in Philadelphia in what is expected to be one of his final major speeches as president to the nation. Other speakers include family members of mass shooting victims, Clinton’s vice presidential pick Tim Kaine and Vice President Joe Biden, who at one point considered running against Clinton in the 2016 race but ultimately decided to stay on the sidelines. 

The third day of the convention opened at 4:30 p.m. Obama was scheduled to speak after 10 p.m. The theme of the night is "working together." You can watch the speeches at the DNC website live here. Bill Clinton addressed the DNC Tuesday night, while first lady Michelle Obama spoke Monday night. 

White House Press Secretary Josh Earnest said the president spent weeks on his speech. Obama previously endorsed Clinton in June when she cinched enough delegates to unofficially become the Democratic presidential nominee after beating Bernie Sanders in California. He has been a vocal critic of Republican nominee Donald Trump, questioning his temperament and leadership abilities. 

The full list of speakers includes:

-Erica Smegielski. Her mother, Dawn, was the principal of Sandy Hook Elementary and was killed during the 2012 mass shooting in Connecticut. She is now a gun control advocate. 

-Felicia Sanders & Polly Sheppard. They are among the survivors of the Mother Emanuel Church shooting in Charleston, South Carolina in 2015.

-Jamie Dorff. Her husband, Patrick Dorff, was an Army helicopter pilot from Minnesota who died while on a rescue mission in northern Iraq.

-Vice President Joe Biden

-President Barack Obama
