He hasn’t been vetted yet. Once info. comes out on his role in the K Street project, it will all hit the fan.

At the center of all this was Santorum. According to Confessore, Santorum conducted weekly breakfasts with lobbyists, and occasionally Congressmen and White House staff, during which he attempted to match Republican Hill staffers with K Street job openings.
As Confessore put it, “Every week, the lobbyists present pass around a list of the jobs available and discuss whom to support. Santorum’s responsibility is to make sure each one is filled by a loyal Republican—a Senator’s chief of staff, for instance, or a top White House aide, or another lobbyist whose reliability has been demonstrated.” The group refused to meet with Democrats, and threatened sanctions against lobbies that did.
