This was the rumor. It’s not clear to me that either Clinton wanted this or Bibi for that matter. I’d certainly think that if pro-Pollard forces had decided to “leak” this information, Bibi wouldn’t have wanted to deal with a political backlash if he downplayed how important it was to him.
Oh, I don't think Clinton cared one way or the other. It was merely a bargaining chip to him. I think that Netanyahu had little power to ask much of anything in the end.
