Jay-Z urges people to vote in Obama campaign ad

Jay-Z has urged people to use their right to vote in the latest advert released by Barack Obama's presidential campaign.

Jay-Z says in the video, "When the president got into office initially, what he represented to a nation of kids was hope. You know, the hope of people all across the country, who would look and see themselves, and the possibilities".

During the ad the star - a friend of the President - says he believes the US people can now see the "power of our vote" thanks to Mr Obama.
