Updated The ailing cable news channel CNN on Wednesday abruptly ended “John King, USA,” its 6 p.m. political news program.
The program will be replaced at the end of the month by “The Situation Room with Wolf Blitzer,” which will expand from two hours to three hours. Mr. Blitzer’s program currently precedes Mr. King’s, beginning at 4 p.m.
Ken Jautz, the executive in charge of CNN, said in an internal memo that the schedule change was made to improve political coverage this year. Mr. King will be the network’s top campaign correspondent for the remainder of the presidential election cycle. He had a similar role during the 2008 presidential election cycle.
