Vice President Joe Biden takes the stage at the DNC

PHILADELPHIA (AP) Vice President Joe Biden says Hillary Clinton's election will have a major impact on young girls. He says when she walks into the Oval Office as president, "it will change their lives."

Biden is vouching for Clinton in a speech to the Democratic National Convention. He recalls his weekly breakfasts with Clinton when she served as secretary of state during the Obama administration.

Biden says everyone knows that Clinton is smart and tough but he says, "I know what she's passionate about. I know Hillary."

Vice President Joe Biden is paying tribute to his late son Beau, who introduced him at the 2008 Democratic National Convention.

Beau Biden went on to become attorney general of Delaware. He died in 2015 after a battle with cancer.

The vice president tells delegates in Philadelphia that the nation got to see "what an incredibly fine young man" Beau Biden was when he nominated his father for vice president.

Biden says his challenge in dealing with his son's death makes him appreciate "the unbreakable spirit of the people of America" who deal with problems every day with "so much less support," but still "put one foot in front of the other."

The vice president was considered to be a potential 2016 presidential candidate, but cited his son's death as a reason he wasn't up for a national campaign.
