Former President Barack Obama is poised to endorse Vice President Kamala Harris as the Democratic nominee for president, sources told CNN. This endorsement comes at a crucial time, as Harris's campaign gains traction following President Joe Biden's decision not to seek re-election. Obama, who has maintained regular communication with Harris, is expected to publicly support her candidacy soon, a move that could significantly bolster her campaign.

The news, initially reported by NBC News, indicates that Obama has been a steady advisor to Harris, offering guidance and serving as a sounding board throughout her political career. An adviser revealed that Obama believed it was essential for the Democratic Party to have a transparent process for selecting their nominee, and he is impressed with Harris's campaign thus far.

Obama's expected endorsement follows his previous role in supporting Biden's re-election efforts, where he participated in numerous fundraisers and public conversations, raising millions of dollars. His forthcoming endorsement of Harris underscores his commitment to unifying the Democratic Party and ensuring a strong candidacy against the Republican opponent.

The Democratic National Committee (DNC) has moved swiftly to solidify Harris's position as the presumptive nominee. The party recently adopted new rules for the nomination process, with voting set to begin on August 1. The official nomination will take place at the Democratic National Convention in Chicago from August 19-22, where ceremonial votes for president and vice president will be conducted.

Harris's campaign has already received significant endorsements from major labor unions, including the American Federation of Teachers (AFT), which boasts 1.7 million members. The AFT delegates voted to endorse Harris, reflecting her growing support among key Democratic constituencies. Harris is scheduled to deliver the keynote speech at the AFT national convention in Houston, further cementing her connection with the union's members.

High-profile endorsements have been pivotal in maintaining the momentum of Harris's campaign. Celebrities such as George Clooney, Barbra Streisand, Spike Lee, Robert De Niro, and Melinda French Gates have publicly supported her, contributing to record fundraising levels. Harris's first campaign video, addressing issues like gun violence, healthcare, and abortion rights, has also been well-received, with Beyoncé's song "Freedom" as its soundtrack.

Obama's endorsement is expected to be a significant boost for Harris. His influence and advice could prove invaluable as she navigates the final months of the campaign. Michelle Obama, the former first lady, is also reportedly supportive of Harris's candidacy, adding another layer of high-profile endorsement to the campaign.

While Harris's campaign gains momentum, she faces continued attacks from former President Donald Trump. At a recent rally in Charlotte, North Carolina, Trump criticized Harris, calling her "the most incompetent and far-left vice-president in American history."
