Jill Biden has been a crucial figure in Joe Biden's political career, often seen as his closest adviser.

She has been instrumental in keeping him in the presidential race, even after a disastrous TV debate with Donald Trump.

Despite facing pressure from high-profile Democrats to step down, Joe Biden finally decided to drop out of the presidential race after a closed-door meeting with his inner circle, including Jill and their four closest advisers.

Joe, 81, was at his beach home on a Sunday with Jill and his closest aides—chief strategist Mike Donilon, counselor to the president Steve Ricchetti, deputy chief of staff Annie Tomasini, and senior adviser to the first lady Anthony Bernal—when he made the decision.

The First Lady, 73, has been hailed as Joe's closest adviser and the only person who has ultimate influence over him.

She has been a driving force in his decision to keep campaigning despite his ailing health.

Jill Biden has loyally stood by her husband's side throughout his political career, acting as his closest adviser and defending him in the face of public scrutiny.

She has spent the last few months trying to help Joe salvage his campaign as his health has taken center stage.

She was seen escorting the confused President off the stage following his car-crash debate with Donald Trump.

Jill has stood by Joe throughout his decades-long political career, which saw him serve as a senator, Vice President, and now as commander-in-chief.

She was by his side at the beach house on Sunday, along with their closest advisers, when Joe officially dropped out of the race.

Ricchetti and Donilon brought devastating new data that helped Joe make up his mind.

They said the latest internal campaign polling showed he could no longer beat Trump.

Joe's decision was made soon after, and he asked Ricchetti and Donilon to start drafting a letter and begin the process of making a public announcement.

The president also began telling his family and made separate phone calls to Kamala Harris, White House chief of staff Jeff Zients, and his campaign chair Jen O'Malley Dillon to inform them of his decision.

Elizabeth Alexander, Jill's communications director, claimed that even down to the last hours of the decision, the First Lady was supportive of whatever road Joe chose.

However, Jill's role in Joe's candidacy has come under serious scrutiny in recent months amid growing fears over Joe's age and health.

Analysts have claimed that she is one of Joe's top advisers and can wield the most influence over him.

Jill has frequently said that it took her some time to decide to marry Joe.

The then-senator proposed to Jill five times before the couple married in 1977.

Joe's relationship with Jill began after his first wife and daughter died in a car crash that injured his two sons.

Jill continued to support Joe throughout his career but played a key role in his decision not to run for president in 2004.

Throughout her husband's presidency, she has maintained her role as a professor of English and writing at Northern Virginia Community College, where she has taught since 2009.
