Edwards and Nunn on Obama's shortlist
Former Senators John Edwards and Sam Nunn are on a list of potential running mates for US Democratic presidential candidate Barack Obama, according to a congresswoman.
Representative Carolyn Cheeks Kilpatrick, a Michigan Democrat who leads the Congressional Black Caucus, says members of her caucus asked her to forward the names of Mr Edwards and Mr Nunn when she met with Mr Obama’s vice presidential search team.
