(NewsNation) — Vice President Kamala Harris called President Joe Biden’s decision to withdraw from the president race a “selfless and patriotic act.”

In a written statement, Harris said “President Biden is doing what he has done throughout his life of service: putting the American people and our country above everything else.”

Since then, Harris has been busy reaching out to key Democratic officials, senators and governors to shore up support, according to a source speaking to NewsNation.

After announcing his decision to leave the race, Biden posted on his X account a short statement saying “I want to offer my full support and endorsement for Kamala to be the nominee of our party this year. Democrats — it’s time to come together and beat Trump. Let’s do this.”

Biden followed up with an X post linking to what is still called the Biden-Harris campaign site and urged people to donate to the campaign.

Thanking Biden for his leadership and service, Harris called her time as vice president “a profound honor,” and said he intends to “earn and win” the Democratic presidential nomination.

“I will do everything in my power to unite the Democratic Party—and unite our nation—to defeat Donald Trump and his extreme Project 2025 agenda,” she wrote.

“We have 107 days until Election Day. Together, we will fight. And together, we will win.”

Vice President Kamala Harris’ full statement

“On behalf of the American people, I thank Joe Biden for his extraordinary leadership as President of the United States and for his decades of service to our country. His remarkable legacy of accomplishment is unmatched in modern American history, surpassing the legacy of many Presidents who have served two terms in office.

“It is a profound honor to serve as his Vice President, and I am deeply grateful to the President, Dr. Biden, and the entire Biden family. I first came to know President Biden through his son Beau. We were friends from our days working together as Attorneys General of our home states. As we worked together, Beau would tell me stories about his Dad. The kind of father—and the kind of man—he was. And the qualities Beau revered in his father are the same qualities, the same values, I have seen every single day in Joe’s leadership as President: His honesty and integrity. His big heart and commitment to his faith and his family. And his love of our country and the American people.

“With this selfless and patriotic act, President Biden is doing what he has done throughout his life of service: putting the American people and our country above everything else.

“I am honored to have the President’s endorsement and my intention is to earn and win this nomination. Over the past year, I have traveled across the country, talking with Americans about the clear choice in this momentous election. And that is what I will continue to do in the days and weeks ahead. I will do everything in my power to unite the Democratic Party—and unite our nation—to defeat Donald Trump and his extreme Project 2025 agenda.

“We have 107 days until Election Day. Together, we will fight. And together, we will win.”
