Former President Bill Clinton and former Secretary of State Hillary Clinton endorsed Vice President Kamala Harris on Sunday via a post on X after President Biden announced his withdrawal from the 2024 presidential race.

Biden also endorsed Vice President Kamala Harris as the nominee for the Democratic Party's convention, which takes place in August.

Harris is expected to present a more active challenge against Republican competitor Trump. 

Hillary Clinton, who was the first woman to secure a major party nomination in 2016, aims to help Harris become the first female US president.

Former President Barack Obama and Michelle Obama are also expected to support Harris.

Full Clinton statement, via X:

"President Biden has capped his extraordinary career of service with a presidency that has lifted America out of an unprecedented pandemic, created millions of new jobs, rebuilt a battered economy, strengthened our democracy, and restored our standing in the world. By any measure, he has advanced our founders' charge to build a more perfect union and his own stated goal of restoring the soul of our nation.

We join millions of Americans in thanking President Biden for all he has accomplished, standing up for America time and again, with his North Star always being what's best for the country.

We are honored to join the President in endorsing Vice President Harris and will do whatever we can to support her.

We've lived through many ups and downs, but nothing has made us more worried for our country than the threat posed by a second Trump term. He has promised to be a dictator on day one, and the recent ruling by his servile Supreme Court will only embolden him to further shred the Constitution. Now is the time to support Kamala Harris and fight with everything we've got to elect her. America's future depends on it."
