Update: After a bit of Internet sleuthing, I have found who appears to be behind the video: The publishers of a children's book titled, I Am Barack Obama by Charisse Carney-Nunes. A cover of the book is placed on an easel to the left of the children and the video was originally posted on the publisher's YouTube account in observance of Father's Day.
From their Web site, a description of the book followed by a review:
I Am Barack Obama is not a book about Barack Obama. Rather, it allows children to see themselves through the inspirational story of President Obama growing up as an ordinary child asking, "Who will change the world?" Ultimately, he realizes that he will. I Am Barack Obama highlights for children their personal power to change the world. In the backmatter, children share stories of the possibilities for their lives, as they aspire to the greatness they have seen in Barack. I Am Barack Obama is also the first children's digibook available interactively along with its companion print edition.
Children must be empowered to know for sure that they can change the world. Charisse has captured this incredible moment in history by writing a book that allows young people to see themselves in President Obama. To me and so many others, Barack Obama represents intelligence, judgement, courage and service. Yet, the power in I Am Barack Obama is not in Barack himself. The power, instead, is in each and every child who finds their purpose and manifests a new destiny through Barack's example.
