"I think I'm incredibly comfortable with that program," said Zucker. "The network seeks, and does an incredibly good job seeking, other points of view, but obviously Keith plays a major role in the voice, certainly in that hour and on the network."
Zucker described Olberman's role as that of "an editorial page."
"For most of its day [MSNBC] is the rest of the front section of the newspaper and then brings an editorial point of view from its editorial page at 8 o'clock at night," he said.
