Today is Constitution Day, so why not celebrate by … enjoying a constitutional rap.

ThanksUSA, a non-profit that provides scholarships to the children and spouses of active duty military personnel, is currently sponsoring a music video contest.

In honor of Constitution Day on September 17, 2014, we challenge teachers and students across the country to get involved by creating their own music videos about the Bill of Rights and the freedoms it provides to all Americans.

The co-founders of ThanksUSA, teenaged sisters Rachel and Kelsi Okun of McLean, VA., recently co-wrote and performed an educational music video called “Con Rap” – rapping the Bill of Rights, literally.
