Jill Biden says she will 'continue to fight' for Joe Biden after his disastrous debate. Here's a timeline of their relationship.

Joe was a 33-year-old US senator, and Jill was a 24-year-old college senior. Both had been married before. Joe's wife and daughter died in a car crash in 1972, leaving him a widower with two sons, and Jill and her husband filed for divorce in her junior year. 

"I was a senior, and I had been dating guys in jeans and clogs and T-shirts, he came to the door and he had a sport coat and loafers, and I thought, 'God, this is never going to work, not in a million years,'" Jill told Vogue. "He was nine years older than I am! But we went out to see 'A Man and a Woman' at the movie theater in Philadelphia, and we really hit it off."

When she got home from the date, Jill told Vogue, she called her mother and said, "Mom, I finally met a gentleman."

"I said, 'Not yet. Not yet. Not yet,'" Jill told Vogue of Joe Biden's proposals. "Because by that time, of course, I had fallen in love with the boys, and I really felt that this marriage had to work. Because they had lost their mom, and I couldn't have them lose another mother. So I had to be 100 percent sure."

When she did eventually agree to marry him, they held their wedding ceremony at the United Nations chapel and a reception lunch at Sign of the Dove in New York City. They took sons Beau and Hunter on their honeymoon.

In a video shown at the 2020 Democratic National Convention, Jill said that Ashley's birth made the family "complete."

He announced his presidential run in Wilmington, Delaware.

His short-lived campaign had been enveloped in scandal, with allegations of plagiarizing his speeches and exaggerating his academic records from college and law school, The New York Times reported.

"'I made some mistakes,'' he said as he announced the end of his campaign.

The New York Times described Jill's face as "a study in dejection." Jill later wrote about controlling her emotions in her memoir "Where The Light Enters."

"As a political spouse, I've found that my stoicism often serves me well," she wrote. "In 1988, when Joe's first presidential campaign started to look bleak, people were constantly looking for cracks in our team. We all felt scrutinized, but I refused to show weakness."

Joe had a pulmonary embolism later that year as he recovered. In her book, Jill writes about watching as "EMTs carried him down the steps of our house on a stretcher."

She became Dr. Jill Biden.

"She gave me back my life," he wrote. "She made me start to think my family might be whole again."

The "bromance" between the two politicians went viral.

Joe supported her career, too. She made history as the first known second lady to hold a full-time job, teaching English at Northern Virginia Community College.

"As second lady, she was teaching full time for eight years, 15 credits a semester," Joe said in a video shown at the 2020 Democratic National Convention.

"I said, 'I know I can do both jobs,'" she said.

She encouraged students to call her "Dr. B.," The Los Angeles Times reported. 

The plaque reads "Joe loves Jill. Valentine's Day 2010."

They took other trips together, such as attending the 2010 Olympics in Vancouver.

An ABC News camera panned to Joe, who could be seen laughing good-naturedly at the unintended double entendre as the audience cheered.

"It's in my remarks, really," she said, before continuing with her speech amid chuckles from the crowd.

"After Joe was elected vice president, people started questioning whether I could keep teaching," she said. "Not Joe. He was there standing by my side saying 'Of course you should. It's who you are, Jill.'"

As they had in 2009, they danced together at more inaugural balls.

Still reeling from the loss, Joe decided not to run for president in 2016.

"After the disappointment of my divorce, I never wanted to feel so out of control of my heart again," she wrote. "But in the months that Joe and I were dating, that desire ran up against a new reality: I was falling in love."

For the first time since 1981, she took a break from teaching to help him on the campaign trail.

Jill was gesturing behind herself as she spoke, barely missing Joe's face as he pretended to dodge. Joe then leaned forward while her arm was outstretched and bit down on the tip of her index finger. She appeared to laugh it off.

Jill later reposted a video on X of the hosts of "The View" discussing the moment, where Meghan McCain said, "I thought it was silly, and they clearly still love each other and are playful," and replied, "Guilty, we do still love each other!"

"Whoa, you don't screw around with a Philly girl, I'll tell you what," he said after the protesters were removed from the stage. "I thought I heard on the news on the way over that the committee in charge of Secret Service decided they have to start providing Secret Service for us. I think that's because they're afraid Jill's going to hurt someone. I tell you what man, I married way above my station."

"Love makes us flexible and resilient," she said in the speech. "It allows us to become more than ourselves, together, and though it can't protect us from the sorrows of life, it gives us refuge, a home. How do you make a broken family whole? The same way you make a nation whole: with love and understanding and with small acts of kindness."

"Jill's a mom — a military mom — and an educator," he said. "She has dedicated her life to education, but teaching isn't just what she does — it's who she is. For America's educators, this is a great day: You're going to have one of your own in the White House, and Jill is going to make a great first lady."

In an interview on "The Late Show with Stephen Colbert," they responded to the controversy.

"That was such a surprise," Jill said of the op-ed. "It was really the tone of it. He called me 'kiddo,' and one of the things I'm most proud of is my doctorate. I mean, I've worked so hard for it. And Joe came when I defended my thesis."

"I got to hand her her doctorate on the stage at the University of Delaware," Joe added.

Colbert jokingly asked if Joe ever wanted to "get out a length of pool chain and go full corn pop" on people who criticize Jill's academic achievements. As he began to answer, Jill interjected with "No! The answer is no!" Joe then quipped, "I've been suppressing my Irishness for a long time."

The Biden family Bible dates back to 1893. He has used it for his swearing-in ceremonies as a US senator and as vice president. 

The president and first lady were traveling to Atlanta for a rally in Plains, Georgia, to meet with former president Jimmy Carter and former first lady Rosalynn Carter.

As they were boarding Marine One on the White House Ellipse, the president bent down and picked a dandelion for his wife. Jill stopped to accept the flower, and she held on to it as she boarded the helicopter.

The Bidens entered the White House with two German shepherds, Champ and Major. Champ passed away at the age of 13 in June 2021, and Major was rehomed due to behavioral issues. 

The Bidens also adopted a cat, Willow, in January 2022.

Commander was moved out of the White House in October 2023 after numerous biting incidents.

While exiting Marine One on Valentine's Day, the first lady was photographed wearing a corsage of what appeared to be white gardenias, her favorite flower.

In an interview with People magazine shortly after Joe took office, Jill shared that the corsages began as a Valentine's Day tradition, and that he had surprised her with a corsage of gardenias at the inauguration.

"I don't know when it started — a long, long time ago. I think it was for Valentine's Day," she said. "I love gardenias and so Joe would buy me a wrist corsage of gardenias. I wore it to school to teach!"

Joe also shared a sweet Valentine's Day message for his wife.

"You're the love of my life and the life of my love, Jilly. Happy Valentine's Day," he wrote on X.

Jill, who appeared on the June-July cover of Harper's Bazaar, told the magazine that she and Biden fight via text in what they call "fexting" to avoid arguing in front of their Secret Service detail — a method they've used since Biden served as vice president.

In one particularly heated exchange, Biden reminded her that presidential communications like texts and emails are kept as part of a historical record of each presidency.

"Joe said, 'You realize that's going to go down in history. There will be a record of that,'" she told Harper's Bazaar. "I won't tell you what I called him that time."

While they do occasionally "fext," Jill also spoke about supporting her husband's work during his presidency.

"I try to be a support for Joe because I don't know how many people are saying to him, 'That was great. That was brilliant.' I try to be that person for him," she said. "Some days, I see Joe and I'm just like, 'I don't know how you're doing it.' It's the pandemic and then it's the war and then it's the economy and then it's the gas prices. You feel like you're being slammed."

The Bidens celebrated their anniversary at their beach house in Rehoboth Beach, Delaware. During their trip, Joe fell off his bike but quickly got back up and chatted with reporters. A White House spokesperson said that the president did not require medical attention.

Jill's support was widely regarded as a determining factor in Joe's decision to run again in 2024.

South Carolina Sen. Dick Harpootlian, a former state party chairman and Biden 2020 finance committee member, told Business Insider in 2022 that "Joe Biden wouldn't have run in '20 if Jill Biden had not wanted him to run and he won't run in '24 if Jill Biden doesn't want him to run."

During the first presidential debate of 2024, Joe spoke with a hoarse voice, offered convoluted answers, and appeared disoriented at times. His poor performance sparked panic among Democrats about whether he should stay in the race.

Jill defended Joe in the face of widespread criticism, telling Vogue that the Biden family "will not let those 90 minutes define the four years he's been president. We will continue to fight."

"When he gets knocked down, Joe gets back up, and that's what we're doing today," Jill said at a New York City fundraiser the day after the debate.

Joe also acknowledged that his age has impacted his debate performance, but remained firm in his commitment to stay in the race.

"I know I'm not a young man, to state the obvious," he said during a rally the day after the debate. "I don't walk as easy as I used to. I don't speak as smoothly as I used to. I don't debate as well as I used to. But I know what I do know: I know how to tell the truth. I know right from wrong. And I know how to do this job. I know how to get things done."
