After weeks of speculation and anticipation, presidential candidate Joe Biden announced on Tuesday that he has officially picked his running mate.

In a history-making announcement, Biden revealed that he had tapped California Sen. Kamala Harris to be his VP Pick.

“I have the great honor to announce that I’ve picked @KamalaHarris — a fearless fighter for the little guy, and one of the country’s finest public servants — as my running mate,” Biden announced in a tweet.

On Wednesday, Biden held his first campaign event alongside running mate Kamala Harris in Delaware.

During their speeches, the two candidates wore masks and kept their distance in keeping with COVID-19 standards.

Speaking about his VP pick, Biden described Harris as coming from an “America’s story.” Biden described Harris as “a child of immigrants” who “knows personally how immigrant families enrich our country as well as the challenges of what it means to grow up Black and Indian-American in the United States of America,” he explained. “And this morning, all across the nation, little girls woke up, especially little Black and brown girls that feel overlooked and undervalued in their communities, but today — today just maybe they’re seeing themselves for the first time in a new way as president and vice presidents.”

In a speech of her own, Harris emphasized the importance of family and urged citizens to vote.  “We need a mandate that proves that the past few years do not represent who we are or who we aspire to be,” she said. “Joe likes to say that character is on the ballot. And it’s true,” she explained. “I’ve had a lot of titles over my career and certainly vice president will be great. But ‘Momala’ will always be the one that means the most.”

Harris’s nomination makes her the first Black and first Indian-American woman on either major party’s presidential ticket.

Harris is a former prosecutor from California who challenged Biden in her own presidential bid last year. Her nomination makes her the fourth woman to appear on a major presidential ballot. Before her, Geraldine Ferraro ran as a Democratic vice presidential nominee in 1984. In 2008, Republican Sarah Palin ran as a vice presidential nominee, later in 2016, Hillary Clinton became the Democratic presidential nominee.

Biden’s choice was one that has long been in the works. In March of this year, he revealed that he would make a point to have a woman as his running mate and in July he announced that he had narrowed his picks down to four Black women.

Kamala Harris was elected to Congress in 2016.

This has been Harris’ first term as a senator. Before, she served as the California attorney general. During her time as AG, Harris formed a lasting friendship with Biden’s late son Beau who was attorney general at the time in Delaware. Writing about Beau’s death, in her memoir The Truths We Hold, Harris recalled that “there were periods when I was taking the heat when Beau and I talked every day, sometimes multiple times a day,” she wrote in her memoir. “We had each other’s backs.”

Biden’s son Beau died in 2015 from brain cancer. Harris attended his funeral.

During his announcement, Biden mentioned Harris’ friendship with his son.

“I watched as they took on the big banks, lifted up working people, and protected women and kids from abuse,” Biden tweeted. “I was proud then, and I’m proud now to have her as my partner in this campaign.”

So far, it seems there are quite a bit of Harris x Biden supporters.

Fans were quick to give their support and applaud her candidacy.

In a tweet acknowledging her nomination, Harris wrote “@JoeBiden can unify the American people because he’s spent his life fighting for us. And as president, he’ll build an America that lives up to our ideals. I’m honored to join him as our party’s nominee for Vice President, and do what it takes to make him our Commander-in-Chief.”

Here’s to 2020 y’all. Get ready to make history.
