Joe Biden gave Kamala Harris a chilling warning on the day of her debate with Donald Trump after she took over the Democratic nomination, according to an upcoming book. 

The president publicly supported Harris’ bid for the White House and backed her campaign platform, but behind the scenes he was more concerned over how she was framing his presidency. 

The moment was recounted in upcoming book FIGHT: Inside the Wildest Battle for the White House by Jonathan Allen and Amie Parnes, which details how Biden attempted to keep Harris on a leash. 

‘He would say publicly that Harris should do what she must to win. But privately, including in conversations with her, he repeated an admonition: let there be no daylight between us,’ the authors wrote. 

After he was forced out of the race following his disastrous debate performance against Trump and questions over his age, Biden reportedly ‘expected Harris to protect his legacy.’ 

On the day that Harris was set to face Trump on the debate stage, ‘Biden called to give Harris an unusual kind of pep talk — and another reminder about the loyalty he demanded,’ the authors wrote. 

Biden reportedly gave Harris a three-word warning: ‘No daylight, kid.’ 

Joe Biden reportedly told Kamala Harris there should be ‘no daylight’ between them during her doomed presidential run as he was more concerned with his legacy than winning, according to a new book 

Biden is said to have called Harris ahead of her debate with Donald Trump in September and given her a three-word pep-talk: ‘No daylight, kid’ 

The book continued that Biden was focused not on ‘whether she won or lost the election’ but on how he would be remembered. 

‘He thought, she would only harm him by publicly distancing herself from him — especially during a debate that would be watched by millions of Americans. 

‘To the extent that she wanted to forge her own path, Biden had no interest in giving her room to do so.’ 

The book is one of several inside looks at the end of the Biden presidency that are set to come out over the summer, with another by journalist Chris Whipple, Uncharted: How Trump Beat Biden, Harris, and the Odds in the Wildest Campaign in History, claiming Biden was so ‘out of it’ he needed fluorescent tape to guide him around. 

In Fight, the authors claim Biden was seen by many as an albatross around Harris’ neck that wore her candidacy down during the election. 

During the bruising election campaign, Biden’s staffers remained with the Harris campaign, making it even more difficult to publicly refute the president.

Sean Clegg, a Harris advisor not trusted by the Biden staffers, was helping her prepare for a joint appearance with Tim Walz when she started listing things that she and Biden accomplished when he stopped her.

‘Wait, wait, wait! Let’s not do this. Let’s not go down memory lane,’ Clegg said, according to an excerpt published by The Hill.

Clegg was reportedly disinvited from future media prep sessions by longtime Dem communications staffer Stephanie Cutter. 

Biden was forced out of the race following his disastrous debate against Donald Trump in June and questions over his age, but upcoming books claim he was still undermining Harris’ candidacy over concerns for his legacy 

Insiders have claimed Biden was an albatross around Harris’ neck during the election 

Previously, Biden was blamed by senior Harris advisor David Plouffe for refusing to drop out earlier in the race after his June debate disaster.

Plouffe claimed no Democratic candidate could have won without a proper primary process — what he called ‘the cardinal sin’ of this race. 

And he said he was shocked by the internal polling numbers when he finally joined the team after Joe Biden dropped out with less than four months to go, a situation he described as ‘catastrophic.’

‘When I got in, it was the first time I saw the actual numbers under the hood. They were pretty gruesome,’ he told The Atlantic.

‘The Sun Belt was worse than the Blue Wall, but the Blue Wall was bad. And, demographically, young voters across the board—Hispanic voters, Black voters, Asian voters—were in really terrible shape.

‘When the switch happened, some of that stuff got a little bit better, but nowhere near where we ended up or where we needed to be. This was a rescue mission.

‘It was catastrophic in terms of where it was.’
