A feather in President Obama’s cap: His administration scored its first conviction at Guantanamo Bay on Wednesday when Ibrahim al Qosi pleaded guilty to conspiring with al Qaeda and providing material support to terrorists. Ibrahim al Qosi was Osama Bin Laden’s cook and helped Bin Laden escape from Tora Bora. He has been held at Gitmo since 2002 and is just the fourth person to be convicted in a tribunal there.
