The US is demanding that Pakistan allow interviews with three widows of Osama bin Laden. One was in his hide-out when he was killed more than a week ago and all are in custody. That's increasing pressure on a country the US still calls a "key ally." Prime Minister Yousaf Gilani today called it "disingenuous" to blame the army or Inter-Services Intelligence agency for allowing bin Laden to hole up in Pakistan for so long. Meantime, the White House seems to be warning it might soon have evidence of who knew what and when. That's according to David Sanger of the New York Times.
