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.
In the hours since President Joe Biden endorsed Vice President Kamala Harris on Sunday afternoon, she has collected $49.6 million in grassroots donations, the campaign said.

More than 45,000 people gathered late Sunday on a Zoom call organized by Win With Black Women to support Vice President Kamala Harris' campaign.
The group said it raised over $1,500,000 in about 100 minutes.
The call was led by the group's founder, Jotaka Eaddy, and included lawyer Star Jones, Rep. Joyce Beatty and Shavon Arline-Bradley, the president and chief executive of National Council of Negro Women. Guests such as actor Jenifer Lewis and Alpha Kappa Alpha Sorority President Danette Anthony Reed chimed in with words of encouragement and wisdom.
Even after 1 a.m. on Monday, people continued trying to join the call, and donations kept pouring in. Zoom lifted the capacity limit to allow more people to join the call.
"Don't you ever lose faith in Black women," said Dr. Johnnetta B. Cole, a former president of Spelman College.

Vice President Kamala Harris on Sunday morning had multiple phone conversations with President Joe Biden before he announced that he would not be seeking reelection and would instead endorse her, according to a source familiar with her schedule.
Surrounded by family and staff at the vice president's residence, Harris spent more than 10 hours placing calls to over 100 party leaders, members of Congress, governors, labor leaders and leaders of advocacy and civil rights organizations. On each of those calls, Harris made clear that she was extremely grateful for the president's endorsement but plans to work hard to earn the Democratic nomination in her own right, the source said.
One of the calls was to her pastor, Amos Brown III, who, along with his wife, prayed over her, according to the source.
The vice president wore a hooded Howard University sweatshirt, workout sweats and sneakers throughout the day. Amid the many calls, she took time to arrange both lunch and dinner for the assembled aides. The menu was salad and sandwiches for lunch and pizza and salad for dinner. Harris' pizza came with anchovies, her go-to topping, the source said.
