Former President Barack Obama has also endorsed Vice President Harris.
Vice President Kamala Harris wrapped up what has been a whirlwind week in the presidential race with her campaign saying Sunday it has raised more than $200 million in less than a week.
On Thursday night, Harris met with Israeli Prime Minister Benjamin Netanyahu and took the lead in addressing the public about their discussions.
Harris has secured commitments from enough delegates to become the presumptive nominee if they all honor their commitment when voting, according to ABC News reporting.
Ahead of President Joe Biden's announcement that he dropped out of the 2024 presidential election, Sen. Elizabeth Warren, D-Mass., had voiced her support for Vice President Kamala Harris.
"If President Biden decides to step back, we have Vice President Kamala Harris, who is ready to step up, to unite the party, to take on Donald Trump, and to win in November," Warren said.
Former President Donald Trump is rallying against the Democratic Party Sunday, following the announcement President Joe Biden is leaving the 2024 race.
"Crooked Joe Biden is the Worst President, by far, in the History of our Nation. He has done everything possible to destroy our Country," Trump said in a statement on TruthSocial.
"Whoever the Left puts up now will just be more of the same," Trump continued.
Trump's campaign also released a statement Sunday, calling out Vice President Kamala Harris by name, after Biden endorsed her as the next Democratic pick.
"Kamala Harris is just as much of joke as Biden is," the campaign said, adding, "Harris will be even WORSE for the people of our Nation than Joe Biden. Harris has been the Enabler in Chief for Crooked Joe this entire time. They own each other’s records, and there is no distance between the two."
Democratic delegates and donors are say they are "relieved" and "thrilled" that President Biden has made the decision to step down, but they are divided on the best path forward.
"No one I know wants a coronation. In fact, Kamala will be stronger to go through a mini primary and we need to have an alternative or two," one key donor told ABC News.
"We need to put best ticket together and let delegates vote," the donor added. "Not sure it’ll happen but we are trying."
Another delegate and donor told ABC News they are fully behind Harris.
"Now big donor money will start flowing again. His selfless act will save our republic," a second donor said.
