A former diplomat who helped President Clinton negotiate with Yasser Arafat's Palestinian Authority, he's now a member of the International Crisis Group and is open about ongoing conversations with Hamas and others identified by the State Department as "terrorists." Robert Malley has been targeted by some who question Barack Obama's support for Israel. The Obama campaign has defended him as someone who, like hundreds of other experts, provided informal advice in the past, but has no formal role nor will not play any role in the future. Who is Malley? What is the International Crisis Group? Why talk with violent groups committed to the destruction of Israel?
