Former president Barack Obama and first lady Michelle Obama endorsed Vice President Harris for president on Friday, becoming the final key leaders in the Democratic Party to unite behind Harris after President Biden abandoned his bid for a second term.

A video posted on social media shows the Obamas calling Harris to inform her of their endorsement.

“We called to say Michelle and I couldn’t be prouder to endorse you and to do everything we can to get you through this election and into the Oval Office,” the former president says to Harris.

Michelle Obama adds, “I can’t have this phone call without saying to my girl Kamala: I am proud of you. This is going to be historic.”

In a separate statement, the Obamas pledged to “do everything we can” to elect Harris and called on their legions of supporters to join the effort.

They praised Harris’s record of accomplishments, listing each of her previous roles in what could be interpreted as a rejoinder to Republicans who have labeled her a “DEI hire” — a reference to “diversity, equity and inclusion” initiatives often used derisively to suggest that Harris only reached the upper echelon of American politics because of her race and gender.

“But Kamala has more than a résumé. She has the vision, the character, and the strength that this critical moment demands,” they wrote. “There is no doubt in our mind that Kamala Harris has exactly what it takes to win this election and deliver for the American people. At a time when the stakes have never been higher, she gives us all reason to hope.”

Their call with Harris took place on Wednesday. Barack Obama said the Democrats would be “underdogs” but pledged to work hard for her election.

“Bottom line is, we are ready to get to work,” he said during the call, according to a transcript. “We are telling everybody to kick off those bedroom slippers and get off the couch and start knocking on doors and making phone calls.”

Many Republicans seized on the fact that Obama did not mention or endorse Harris in his initial statement responding to Biden’s abrupt exit from the race Sunday.
