Hoekstra is chairman of the House intelligence committtee. For him to associate himself with this information makes it more significant to me than Santorum's involvement.
Substantively, yes, I would agree.
Visually Santorum is by far the most well known of the two and third ranking member of the Republican leadership in the Senate. IMO, they provide needed balance to each other to maximize the revelation's impact.
So how can this not be breaking everywhere? I even glanced at DU to see if see if they've kicked off a counter-thread yet. Nothing.
It's significant that it's Santorum because he's the most in-trouble R Senator and the WH must think this is big to make him the point man on it.
It means many weeks of being on talk shows and giving interviews. It means the WH at least thinks it's a big deal.
