Jay-Z Raps: "I Got 99 problems But Mitt Ain't One"
Jigga slams Barack Obama's rival by changing the lyrics to his hit track...
The tune included the lyrics: "I kissed your sister then I kiss your mama/Usually this time of the day I'm in my pajamas/Well let's vote for the man who got Osama/Forward and away we go!"
Obama himself closed the event with a speech urging the people of Ohio to vote for him in the election.
As well as Jay-Z showing his support, Jigga's wife Beyoncé has also penned an open letter to Obama on her official website, paying tribute to him.
Queen B wrote: "Everyday we see your heart and character, inspiring all of us to give more of ourselves. You are the leader to take us from where we are to where we need to be.
"You are the reason my daughter and nephew will grow up knowing that they can truly be ANYTHING they want to be."
She then conlcuded: "All my respect and adoration, Beyoncé."
