Apple CEO Tim Cook has called on graduates of George Washington University to find their values and commit to living by them to help change the world.

Cook spoke Sunday to 6,000 graduating students on the National Mall in Washington and took a picture of the crowd with his iPhone.

Cook says his predecessor, Steve Jobs, set out to make Apple a company could help people realize their dreams and make the world better. He says Apple's products have empowered people.

Cook says now people who witness injustice and want to expose it now can because they have cameras in their pockets all the time.

The CEO of the world's most valuable company says graduates can do well and do good in the world by staying true to their values.
