Barack Obama has 99 Problems... but Mitt Romney ain't one - video
He may have won mixed reviews for the first pre-election debate against Mitt Romney, but as the song says, he's got 99 Problems, but Mitt ain't one...
Barack Obama first revealed that he is a fan of Jay-Z's music in 2010.
The pair later met at the White House and Jay-Z formally endorsed Obama for the 2012 election a year ago.
Jay-Z and his wife Beyoncé raised $4 million (£2.46 million) for the Obama campaign at a gala fundraising event.
