JACKSON, Miss. — Sen. Kamala D. Harris (D-Calif.) on Sunday endorsed Joe Biden for president, the latest of his former rivals to give a nod to the former vice president's candidacy.

In a statement, Harris said she felt that Biden was best prepared to “steer America through these turbulent times.”

“When I started my run for president, I said America needs a president who reflects the decency and dignity of the American people; a president who speaks the truth; and a president who fights for those whose voices are too often overlooked or ignored,” Harris said in a statement released Sunday morning.

Harris is the sixth former rival to endorse Biden since his commanding victory in the South Carolina primary. Former South Bend, Ind., mayor Pete Buttigieg, Sen. Amy Klobuchar (D-Minn.) and former Texas congressman Beto O’Rourke (D) endorsed Biden in advance of the pivotal slate of Super Tuesday states.

Billionaire Mike Bloomberg endorsed him after dropping out of the race Wednesday, and former Massachusetts governor Deval Patrick endorsed Biden on Friday.

During a debate in June, Harris attacked Biden for talking positively about his ability to work with segregationist senators, and she pointed out his opposition to busing students.

“I do not believe you are a racist. I agree with you when you commit yourself to the importance of finding common ground,” Harris said. “But I also believe, and it’s personal . . . it was hurtful to hear you talk about the reputations of two United States senators who built their reputations and career on segregation of race in this country.”

Since Harris dropped out of the presidential race in December, Biden has heaped praise on her. That continued Sunday morning, when Biden tweeted: “Kamala — You've spent your whole career fighting for folks who’ve been written off and left behind — and no small part of that alongside Beau. From our family: thank you.”

Biden is also frequently asked whether Harris should be his vice presidential pick.

In her statement, Harris spoke kindly of Biden's political career, and of Biden’s deceased son, Beau, who was attorney general of Delaware when Harris held the same position in California.

“I got to know Joe more than a decade ago through his son — my dear friend, the late Delaware Attorney General Beau Biden,” Harris said in the statement. “As attorneys general during the financial crisis, Beau and I were leaders in the fight to take on the biggest banks in the nation and secure billions of dollars in relief for homeowners across the country. And I can tell you that Beau inherited his strength of character, selfless courage, and commitment to public service from his father, Joe.”

On Saturday, during a speech in St. Louis, Biden insisted that his campaign could be a landing spot for Democrats whose initial choice for president had dropped out of the race. He curiously included Harris’s supporters: “To all of Amy’s folks. To all of Pete’s folks. To all of Kamala’s folks who have — Beto’s folks. I tell you what, what a gigantic difference it has made.”
