Joe Biden made an emotional speech on the first night of his party's national convention as he backed Kamala Harris to succeed him into the White House.

A month after he withdrew from the race to be his party's presidential nominee following a series of disastrous media appearances and gaffes, Biden wiped away tears as his time in the Oval Office comes to an end. He backed the party's new nominee, Harris, and said appointing her as his vice-president was the "best decision I made my whole career".

But Biden also took the time to attack "loser" Donald Trump, the Republican nominee for president, who is bidding for his second term in office.

Trump, meanwhile, shared several AI-generated deepfake images of Harris - as well as singer Taylor Swift and tech tycoon Elon Musk - in an effort to drum up support.

Joe Biden denied he is "angry" with Democrats who tried to remove him as their candidate ahead of this year's US election.

The outgoing US president was seen wiping away tears as he walked out to deliver a speech on the opening night of the Democratic National Convention in Chicago, Illinois, on Monday night.

In his speech, he said: "I love the job, but I love my country more. All this talk about how I'm angry at all the people who said I should step down - that's not true. I love my country more and we need to preserve our democracy."

Kamala Harris made a surprise appearance on stage at the Democratic National Convention on Monday, stepping out to the sounds of Beyonce’s “Freedom”.

She said: "This is going to be a great week, I want to kick us off by celebrating our incredible president Joe Biden."

Harris, who will be accepting the party’s nomination for the presidency this week, said the crowd of Democratic delegates and supporters in the United Center arena displayed the “beauty of our great nation".

The crowd at the Democratic National Convention broke into loud chants of "lock him up" after Hillary Clinton assailed former president Donald Trump for his legal woes.

It was a spin on "Lock her up," one of the constant refrains of Trump's presidential campaign against Clinton in 2016.

Trump frequently whipped up his supporters with attacks on Clinton's record as secretary of state, including her use of a private email server, and he vowed to put her in prison.

Clinton, 76, did not respond to the chants from Democrats but stood at the podium silently, smiling and nodding until the audience quieted down.

Donald Trump has shared several AI-generated images of Taylor Swift and her fans vowing their support for his presidential campaign, even though the singer has not endorsed him.

The AI-made images Trump shared over the weekend depict a series of young, smiling women in “Swifties for Trump” T-shirts, as well as one that shows Swift dressed as Uncle Sam encouraging people to vote for the Republican presidential nominee. Each image is a screenshot from X, formerly Twitter, and was originally posted by rightwing accounts with a history of sharing misinformation.

Trump has also posted an AI-generated image that depicted Kamala Harris holding a communist military rally and a deepfake video of him dancing with X owner, Elon Musk, who has endorsed him.

Donald Trump plans to offer a job to his billionaire buddy Elon Musk if elected.

His announcement followed a campaign event in York, Pennsylvania, where Trump said he would be open to assigning a cabinet or advisory role to Musk, the Tesla Motors chief executive and owner of X, formerly Twitter.

“He’s a very smart guy. I certainly would, if he would do it, I certainly would. He’s a brilliant guy,” Trump said.

The pair recently conducted a two-hour online chat together on X.
