WASHINGTON — President Biden was rattling off an inventory of his priorities for a coronavirus reduction invoice in certainly one of his first conferences with reporters as commander in chief when he stopped midsentence to right himself.

These gadgets, Mr. Biden stated, are what “we predict the priorities are,” placing the emphasis on the pronoun. Then, turning to face Vice President Kamala Harris, standing just a few socially distanced ft behind him, he apologized.

It was a uncommon slip for the president, who has labored to incorporate Ms. Harris in practically all his public appearances, and stress that she is a full companion within the selections he makes. These recurring scenes are probably the most tangible results of Mr. Biden’s efforts — and a presidential directive — to deal with Ms. Harris, the primary lady and Black vice chairman, as an equal stakeholder as he works to knit collectively the nation’s political rifts, handle racial inequalities and convey the coronavirus pandemic to heel.

“The president has given us clear directions,” Ron Klain, Mr. Biden’s chief of workers, stated in an interview. “Our objective is to get her on the market as a lot as we will.”

Ms. Harris’s relationship with the president was solid by the bare-knuckle politics of the Democratic major marketing campaign, when she emerged as certainly one of Mr. Biden’s most vocal opponents. A shocking chemistry with Mr. Biden made them working mates and now that relationship can be essential in enabling Ms. Harris to outline herself in what the historian Arthur Schlesinger Jr. stated has proved “to be a job of spectacular and, I consider, incurable frustration.”

“She went from this failed marketing campaign to getting the golden ticket, because the chief surrogate for a man who appreciates the position of vice chairman, and goes to place her on the market on this historic position,” stated Gil Duran, a former aide to Ms. Harris when she served as California legal professional normal. “So the query is: What does she do with this reset?”

The reply is a piece in progress.

The vice chairman has already made her presence identified, most lately Friday morning, when she traveled to Capitol Hill earlier than dawn to solid a tiebreaking vote within the Senate, clearing the way for Mr. Biden’s $1.9 trillion coronavirus stimulus bundle to maneuver ahead with out Republican assist.

And because the barrier-breaking a part of the partnership, Ms. Harris has assumed the burden of dwelling as much as the expectations of voters, particularly individuals of shade, who helped put Mr. Biden within the Oval Workplace. It’s a burden Mr. Klain says she has borne “with grace” even because it weighs closely on her. Others say it’ll take time for her to chart her personal course.

For now, the vice chairman’s workers advisers appear decided to cement and spotlight her bond with Mr. Biden by way of their joint appearances, whilst they search to keep away from letting Ms. Harris develop into a inflexible, mannequinlike determine standing by the president’s aspect, a lot as Vice President Mike Pence did all through the previous 4 years.

For a mannequin, Ms. Harris must look no additional than Mr. Biden. In eight years as vice chairman, he carved out his personal position beside President Barack Obama, however not earlier than overcoming a relationship that was, at first, stiff and formal.

Mr. Biden and Ms. Harris are off to a sooner begin. They’ve spent way more time collectively than their predecessors — normally 4 to 5 hours a day within the White Home, aides say — partially as a result of the coronavirus pandemic has restricted their journey.

Ms. Harris and Mr. Biden normally start the day receiving the President’s Every day Temporary collectively within the Oval Workplace, a convention reinstated for the reason that departure of President Donald J. Trump, who had little curiosity in it. Additionally they shortly embraced the concept of a weekly lunch within the White Home as a personal alternative to construct belief and share ideas.

In building her own staff, Ms. Harris chosen individuals who she knew had good relationships with the president and his crew. She selected Tina Flournoy, who has shut ties to Mr. Klain, to run her workplace. Ashley Etienne, a former adviser to Speaker Nancy Pelosi, is her communications director.

Ms. Harris additionally knew that the president held Symone Sanders, who labored as press secretary to Senator Bernie Sanders’s 2016 presidential marketing campaign earlier than becoming a member of the Biden marketing campaign, in excessive regard. Ms. Sanders is now her press secretary.

Aides to the vice chairman repeatedly burdened that every one of her public occasions and messages had been intently coordinated with members of Mr. Biden’s crew. A visit by Ms. Harris last week to the Nationwide Institutes of Well being to thank scientists and obtain her second dose of the coronavirus vaccine was paired with a speech later within the day by Mr. Biden during which he introduced the acquisition of 200 million additional doses of the vaccine.

That look made a long-lasting impression within the district of Consultant Joyce Beatty, Democrat of Ohio and chairwoman of the Congressional Black Caucus. In an interview, Ms. Beatty stated that her telephone lit up with calls from constituents who had been newly interested in getting the vaccine themselves after photographs of Ms. Harris receiving the shot hit the web.

Black People are practically three times more likely to die from the coronavirus than white People, based on knowledge from the Facilities for Illness Management and Prevention, however white People usually tend to obtain the vaccine, partially due to systemic racism current in well being care establishments. The sight of a Black lady receiving the vaccine, Ms. Beatty stated, “gave individuals hope and gave individuals training.”

These moments, during which Ms. Harris connects with individuals across the nation, are essential to any future she might need past the administration. However they’re additionally in keeping with the messages that Mr. Biden hopes his vice chairman — as a girl, a minority and a technology youthful — can ship on behalf of his agenda.

However, as Mr. Biden properly is aware of, the extra alternatives there are to carve out a separate identification as vice chairman, the extra possibilities there are to make a large number. As vice chairman, Mr. Biden’s loquaciousness steadily caught the tightly scripted Obama White House off guard. At instances, together with in 2012 when he voiced support for gay marriage earlier than Mr. Obama did, Mr. Biden would toss the script fully.

When Ms. Harris sat for an interview last week with a West Virginia tv station, her assist for the president’s $1.9 trillion coronavirus reduction plan was interpreted as an try and put strain on the state’s Democratic senator, Joe Manchin III, who took offense and expressed annoyance that he had not been given a heads-up.

And in a minor flub throughout the identical interview Ms. Harris promoted the clearing of “deserted land mines” in West Virginia — not “deserted mine lands” — as a job creation effort within the state.

White Home officers had been shortly in contact with Mr. Manchin to do injury management, wallpapering over the flap by publicly praising Mr. Manchin’s worth to the Biden-Harris agenda.

Ms. Harris has additionally confronted questions on members of her household taking advantage of their relationships along with her. Experiences that Ms. Harris’s stepdaughter acquired a modeling contract every week after Inauguration Day raised eyebrows even among the many president’s allies. And a enterprise run by Ms. Harris’s niece that sells Harris-themed merchandise has been an moral concern for Mr. Biden’s aides for the reason that marketing campaign. The White Home has stated that her identify won’t be used for business actions that will “suggest an endorsement or assist,” based on a spokeswoman.

That has not diminished the president’s view of Ms Harris. White Home officers stated Mr. Biden was keen to place her to work, a lot the best way Mr. Obama put him accountable for the financial restoration program in early 2009. However the truth that the president doesn’t intend to assign her a particular portfolio instantly inevitably elicited some questions on her position within the administration.

Mr. Biden has as an alternative handed Ms. Harris a flurry of high-profile duties of their first two weeks in workplace. Simply hours after the president introduced on Inauguration Day that america deliberate to rejoin the World Well being Group, the vice chairman was on the telephone with Dr. Tedros Adhanom Ghebreyesus, the director normal of the group, reaffirming the brand new administration’s assist after Mr. Trump’s sustained assaults on the premier world well being establishment.

The decision despatched an early message that she speaks for Mr. Biden on a few of his most crucial priorities, however Ms. Harris has not been shy about urgent Mr. Biden on her personal. Prior to now weeks, aides to the president and vice chairman stated she had repeatedly pushed for extra deal with how the administration’s insurance policies would have an effect on much less advantaged individuals in city and rural communities which are usually neglected.

Throughout an Oval Workplace assembly with Mr. Biden and his advisers on their first Monday within the White Home, Ms. Harris pressed Jeffrey D. Zients, the coronavirus response coordinator, to offer extra element about using cell vaccination facilities to make sure that poor individuals dwelling in distant areas would be capable to be protected towards the virus.

“The vice chairman pushed us laborious, in an excellent method, on are there sufficient cell models accessible? As we wrapped up that assembly, she pushed me on, ‘The place we’re on cell vaccination models? What number of are we going to have, in what time frame? Are they going to have the ability to attain rural communities and concrete communities? How a lot progress have you ever made?’” Mr. Zients stated.

That form of persistence has left a deep impression on Mr. Biden, his aides say.

It was simply hours after Ms. Harris peppered Mr. Zients with questions that the president caught himself taking sole credit score for his coronavirus reduction plan on the stage with Ms. Harris. Mr. Klain, who has served two vice presidents as chief of workers, stated the occasion was extra proof that Mr. Biden had an instinctual understanding of how these moments may really feel.

“She begins with a president who has been there and understands what it feels wish to be the individual standing behind two steps again at a public occasion,” Mr. Klain stated. “I believe he has this empathy for her state of affairs that’s distinctive.”
