Donald Trump's eldest granddaughter Kai donned a dazzling sequined dress during her grandfather's celebratory speech Wednesday. 

The speech was aired around 3am, and served as a sort of victory lap for the former president as a win looks to be in the cards.

As he spoke, the 17-year-old daughter of Donald Trump Jr. stood at attention - flanked by Trump's daughter Ivanka and son-in-law Jared Kushner.

Others there included 18-year-old Baron and mom Melania, as the entire Trump clan came together to put a cap on a successful campaign.

Kai, meanwhile, looked on with her dad  after making her first major appearance a few months at the Republican National Convention. She has since surfaced as an social media sensation.

'We made history for a reason tonight, and the reason is that we overcame obstacles that nobody thought possible,' her grandfather said, after winning Pennsylvania and then Wisconsin.

'And it is now clear that we've achieved the most incredible political thing.'

He proceeded to thank supporters and promise a golden age for the nation when he assumes office, before inviting running mate JD Vance to the microphone.

'I thank you for the trust that you placed in me,' the vice presidential candidate said.

'And I think that we just witnessed the greatest political comeback in the history of the United States of America.' 

Waiting in the wings was Trump's entire family, as the Harris team notably called it quits for the night without calling a meeting. 

The Associated Press had still not called the election for Trump by 3am, but he claimed victory onstage nonetheless.

It meant Trump had won three of the key states of North Carolina, Georgia and Pennsylvania, making victory inevitable.

Four years ago, Trump was a defeated man. Within months he had left Washington D.C. under a cloud after his supporters ransacked the U.S. Capitol.

Allies deserted him and he headed for exile at Mar-a-Lago.

On Tuesday night, he was surrounded by supporters, friends and family at his Florida home as he regained his crown.

He led them out on stage at the Palm Beach County Convention Center where he delivered his victory speech in front of hundreds more supporters who had waited hours to see him.

'Most of all, I want to thank the millions of hard working Americans across the nation who have always been the heart and soul of this really great movement,' he said.
