We already know that Rockefeller has had contacts with our enemies. I bet a lot of these leaks start right in his office.
He even admitted to Chris Wallace that he went to Syria and Iran before we invaded Iraq and 'warned' them we were going to do this.... granted, he's been trying to backpeddle on that admission ever sense, but tie that to the information that was gleened out of the senate intelligence committee where the dems were plotting to undermine the administration and make them look bad -- something about 'we'll only get one shot at this' -- and I think there is some members of that committee who bear investigating.
