A reading of US President Obama's new children's book
US President Barack Obama has released a children's book entitled Of Thee I Sing: A Letter to my Daughters, a 31-page work celebrating Americans.
The book is a tribute to 13 Americans, including scientist Albert Einstein, baseball great Jackie Robinson and painter Georgia O'Keeffe.
It is written in letter form to his daughters, Malia, 12, and Sasha, nine.
School teacher, Lisa Juriga, said the book was "warm and special" after reading the book to her students at Ross Elementary School in Washington, DC.
