Politico’s Michael Calderone writes about the four-hour news block to be hosted by John King starting next month, including how Howard Kurtz‘s program, “Reliable Sources” will fit in.

During Kurtz’ online chat today on WashingtonPost.com, he addressed the issue. “‘Reliable Sources’ will continue as an hour-long media program at 10 a.m. eastern on Sundays, just as it had been,” he wrote. “It will be part of this broader, four-hour block of programming anchored by John King (who, I might point out, was a heckuva reporter for the AP before he made the transition to television).”

Calderone reports Washington bureau chief David Bohrman said on a network conference call that Kurtz “would be used predominately in the 10 a.m. hour.”

During The Situation Room this afternoon, Wolf Blitzer talked with King about the new program. King said “Reliable Sources” would “absolutely” continue. Insiders tell us King will play a role in the program as well.

As for what to call the four-hour show, King said to Blitzer: “We’re working on the name now. We should have a contest.” We’re ahead of you John. TVNewser has already thought of that.
