ABC has put Karen Sisco on hiatus, but the network promises the low-rated critical darling will return to the schedule in March. In its Wednesday/10 pm timeslot, ABC will debut the latest edition of Celebrity Mole beginning Jan. 14 — the same night The Bachelorette premieres. Meanwhile, Stephen King's Kingdom Hospital — ABC's 15-hour limited series — will bow March 3 with a special two-hour installment.
