Westin just recently turned 58 and says his reason behind the resignation is so that he may pursue other opportunities. He has come to the conclusion that after 13 years of being the longest-reining U.S. television network news division chief it is time for him to move on.

"This is the right time for me," Westin wrote in a staff memo given to the Associated Press.
