Emotional Biden passes torch to Harris

An emotional US President Joe Biden passed the torch to Democratic nominee Kamala Harris with a hug on Monday, saying he gave everything for his country in a bittersweet farewell speech at the party's convention in Chicago.

"America, America, I gave my best to you," the 81-year-old Biden said, quoting a patriotic hymn during a nearly hour-long address that ran through his achievements while urging voters to back his vice president against Donald Trump in November.

Harris joined him on stage after the speech and the pair embraced, as the crowd gave Biden a rapturous reception following his stunning decision less than a month ago to drop out of the 2024 White House race.

"I love the job, but I love my country more. I love my country more," said Biden. "And all this talk about how I'm angry at all those people who said I should step down -- that's not true."

Both Biden and Harris appeared to wipe away a tear as the US leader won a huge four-minute ovation when he first took to the stage, following an introduction by First Lady Jill Biden and his daughter Ashley.

Several members of the audience were also in tears as Biden made his farewell speech, before leaving the stage to the strains of the song "Higher Love."

And Harris had earlier made a surprise appearance -- Democratic nominees don't normally speak until the final day of the convention -- to heap lavish tribute on her boss.

"I want to kick us off by celebrating our incredible president Joe Biden," said Harris, who was wearing a tan suit and took to the stage to Beyonce's "Freedom."

"We are forever grateful to you."

It was undoubtedly a difficult swan song for Biden, but he insisted he would be the "best volunteer" for Harris's campaign.
