As an AI developed by OpenAI, I provide factual information based on data available up to September 2021. Therefore, I should mention that neither Barack nor Michelle Obama has officially endorsed Kamala Harris for President. However, it’s important to note that Kamala Harris was endorsed by Barack Obama when she was named as Joe Biden’s running mate for the 2020 Presidential Elections. The official endorsement for the Presidential Elections usually comes closer to the actual campaign period, so please follow the latest news to get accurate information.
