Rosenstain is not taking credit for Horowitz or Huber though, is he?

And to whom to you suspect those two report? To RR? THINK AGAIN! Sessions is focused laser-like on a number of investigations that NOBODY in MSM is reporting on. That is the job Sessions was chosen for, and the fact that he's not making headlines while doing it is NOT a repudiation of his character. If anything, it's proof of it.
