Kamala Harris gains momentum against Donald Trump as Obama endorses her.

• Kamala Harris received the endorsement of former Presidents Barack and Michelle Obama for the presidency.
• A video of a brief phone call between the Obamas and Harris was released by the Harris campaign, announcing the news.
• The video deviated from the conventional format of political endorsements, aligning with the evolving political identity of the Harris campaign.

The former first family, Barack and Michelle Obama, publicly supported Vice President Kamala Harris for president in a video released by her campaign on Friday.

A 55-second video depicts the vice president taking a phone call while walking backstage at an event and getting into her motorcade.

Harris greets both of them with warmth, saying, "Aww, hi, you're together! It's great to hear you both."

"Michelle Obama says, "I can't have this phone call without telling Kamala that I am proud of her and that this is historic.""

The former president declares, "Michelle and I are proud to endorse you and will do everything in our power to help you win the election and take office."

Harris expresses gratitude for their companionship and remarks, "Let's enjoy ourselves with this."

Any speculation that Harris, the de facto Democratic presidential nominee, might not have the full support of the most popular couple in Democratic politics was put to bed by the highly anticipated endorsements.

The Obamas' endorsement of Kamala Harris occurred after the party's leading figures had already publicly supported her, following President Biden's July 21 announcement that he would not run for re-election.

This week, NBC News reported that Barack Obama has been in touch with Kamala Harris via phone and has given her advice on how to strengthen her campaign team, utilizing the resources of the former Biden campaign.

In the upcoming summer and fall, both Obamas are predicted to campaign on behalf of Democrats, particularly to energize voters who are already passionate about Harris.

The Democratic party's upcoming convention in Chicago in August is likely to feature speaking slots for both Barack and Michelle Obama, who have not spoken publicly since the 2016 election.

In modern politics, the rapid growth of the Harris campaign in its first five days is nearly unprecedented.

In the first 24 hours after Biden dropped out, Harris' campaign and the Democratic party raised $81 million, with 500,000 of those donors being first-time contributors to her presidential campaign.

The polling gap between Harris and Trump has narrowed, with Harris trailing Trump by only one point in the New York Times' polling average late Thursday.

The Obama endorsement was noteworthy for how the Harris campaign presented it. A casual video of a private phone call between old friends is vastly different from the typical format of presidential campaign endorsements.

This was not a typical one-sided proclamation of praise for the candidate, as it was released in a more restrained manner.

The video of the phone call was consistent with the evolving political persona of the Harris campaign, which values personal connections, shuns grandeur, and embraces quirkiness.

The low-key packaging of the high value endorsement implies that the Obamas, as powerful speakers, may be holding back their oratorial skills for the right moment to maximize impact.

Harris won't be attending any public events on Friday. However, she's scheduled to campaign in Georgia next week, which could boost Democrats' chances of winning in that state.
