CNN Headline News isn't appointing a replacement for Rolando Santos. (Santos, the "executive vice president and general manager" of the network, is moving to CNNI.) "His duties will be handled" by VP for programming and production Bill Galvin and executive VP Ken Jautz, a CNN rep said.

Thomas Roberts and Kathleen Kennedy's 4 to 6pm newscast is being cancelled. (It's unclear what Roberts and Kennedy will be doing now.) The other two dayparts will expand by an hour each, so Mike Galanos and Christi Paul will anchor from 10am to 2pm, and Chuck Roberts and Linda Stouffer will anchor from 2 to 6pm. The 4 to 6pm staff will be absorbed into the other dayparts.
