In a statement announcing her candidacy for president, Vice President Kamala Harris thanked President Joe Biden for his "extraordinary leadership."

"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," Harris said.

"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," Harris said.

Biden endorsed Harris after announcing his exit on Sunday, saying choosing her as his running mate in 2020 was the "best decision I've ever made."

"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," Harris said.

In a post on X, former Wyoming Rep. Liz Cheney -- a Republican and frequent critic of former President Donald Trump -- praised Biden’s decision to leave the race as "courageous."

"The framers of our Constitution knew that our republic would endure only if our presidents have the character and honor to put duty ahead of self interest," Cheney wrote. "President Biden deserves our gratitude for his decades of service to our nation and for his courageous decision today."

Democratic Sen. Jacky Rosen, from the key battleground state of Nevada, shared a statement on President Biden departing from the 2024 election on Sunday.

“President Biden has served our country in public office with dignity and integrity for decades," Rosen said, adding, "I thank President Biden for his leadership and respect his decision not to seek reelection."

"There is still a lot more work to do on behalf of Nevadans to lower costs, create more opportunity, and defend our fundamental freedoms," Rosen said.

Rosen noticeably did not endorse Vice President Kamala Harris in her statement Sunday.
