EXCLUSIVEKamala Harris' husband Doug Emhoff to enter the spotlight following Jill Biden's shocking step back from the presidential campaign trail

Doug Emhoff will be stepping in for Jill Biden at a series of fundraisers the campaign has scheduled, including one in Martha's Vineyard with David Letterman and one in Paris tied to the Olympics.

The first lady is stepping back from the campaign trail after her husband Joe Biden exited the president race.  

The second gentleman will fill in for Jill Biden at is her upcoming fundraisers in Maine, Martha's Vineyard and Paris, an official with the Harris campaign told DailyMail.com.

Jill Biden had been a prolific fundraiser for her husband's campaign, raising millions of dollars for his re-election effort.

President Biden also canceled a fundraising trip to California and Colorado scheduled for the end of this week.

It's unclear when - or if - the Bidens will fundraiser for Vice President Kamala Harris. The Harris campaign said President Biden's events will be rescheduled.

Jill Biden's team did not respond to DailyMail.com's request for comment. 

Both Joe and Jill Biden were scheduled to be at the Martha's Vineyard fundraiser on Monday, July 29, which also was being hosted by Hawaii Gov. Josh Green. Green said the event was being held at the home of a family friend.

Letterman, who hosted CBS' Late Show for 22 seasons, will still be there. Now, however, he will be with Emhoff. 

The first lady was scheduled to host the fundraiser in Paris on Thursday evening when she arrived in the city for the opening ceremony of the Olympics on Friday. She is leading the U.S. delegation for the event.

Emhoff will head to Paris in August to lead the delegation for the closing ceremony. The fundraiser is expected to be rescheduled for that time frame. 

Jill Biden has not publicly commented on her husband's exit from the 2024 race or his decision to endorse his vice president as his replacement as the party's nominee. 

She retweeted Joe Biden's letter announcing his departure with two hearts and she retweeted without comment his endorsement of Harris.

But that is all that has come from her.

Harris wrapped up enough support to win the nomination within 30 hours and raised over $100 million. Biden's campaign is now the Harris for President campaign. 

President Biden called into his campaign headquarters on Monday, when Harris went to visit staff there. 

'We love Joe and Jill,' Harris said. 

'It's mutual,' Biden interjected from the phone line.

Jill Biden and Kamala Harris are not close although the first lady and Emhoff have a good relationship.

She has never denied a report that she told supporters that Kamala Harris could 'go f**k' herself after the June 2019 Democratic primary debate where the then-presidential candidate attacked Joe Biden for supporting racist bus policies.

According journalist's Edward-Isaac Dovere's book on the 2020 Democratic presidential primary, 'Battle for the Soul: Inside the Democrats' Campaigns to Defeat Trump,' Jill Biden made her feelings very clear about Harris' attack on Biden's position on a controversial busing program in the 1970s. 

Harris attacked Biden for it during the first primary debate, garnering a massive fundraising and publicity boost with her attack.

Jill Biden, who is known to hold grudges, was reportedly not pleased. 

'With what he cares about, what he fights for, what he's committed to, you get up there and call him a racist without basis?' Jill said on a phone call with close supporters a week after the debate, according to multiple people on the call.

'Go f**k yourself.'

During the debate in 2019, which was the height of the Democratic presidential primary, Biden was blindsided by Harris' attacks, which claimed he did not support desegregation of schools by way of busing in the 1970s.

Harris, a half-Indian half-Jamaican daughter of immigrants, reminded Biden that, at the time, she was a beneficiary of the busing system.

'That little girl was me,' she told him.
