The announcement was posted to the Obamas' social media accounts, accompanied by a video of Harris — the current vice president and de facto Democratic presidential nominee — receiving a call from the Obamas offering their endorsement.
“Earlier this week, Michelle and I called our friend @KamalaHarris," “Obama said in his post. "We told her we think she’ll make a fantastic President of the United States, and that she has our full support. At this critical moment for our country, we’re going to do everything we can to make sure she wins in November. We hope you’ll join us.”
In the video, Michelle Obama can be heard saying, “I can’t have this call without telling my girl Kamala: I am proud of you. This is going to be historic.”
In response, Harris thanked them for their friendship over the years. “And we’re gonna have some fun with this too, aren’t we?” she said in the video.“
