The culture of Washington reporting has changed in the wake of the Halperin/Heilemann book.
An exchange I had yesterday with an administration source:
Me: "So we'll do this on deep background, right?"
Them: "Yeah, but not 'Halperin deep background'--deep background."
Me: "Right. I can use the info, but if I want to quote I gotta run it by you first."
Them: "Yes. No book scenes, none of that stuff."
Me: "Yeah, yeah, I got it."
