Actress Jessica Alba uses the Pledge of Allegiance as an example of the campaign in an email to supporters.

"Growing up, my classmates and I started every day with a ritual: We'd stand up, put our right hand over our hearts, and say the Pledge of Allegiance," explains Alba. "To me, that gesture was a promise. A promise to be involved and engaged in this country's future. A promise to work for liberty and justice - and for affordable education, health care, and equality - for all."
