New York says:

According to multiple Fox sources, [Fox News head Roger] Ailes has issued a new directive to his staff: He wants the faces associated with the election off the air — for now. For Karl Rove and Dick Morris — a pair of pundits perhaps most closely aligned with Fox’s anti-Obama campaign — Ailes’s orders mean new rules. Ailes’s deputy, Fox News programming chief Bill Shine, has sent out orders mandating that producers must get permission before booking Rove or Morris.

It doesn't get much lower than that.
