Pulitzer Prize-winning columnist Kathleen Parker is leaving CNN’s embattled primetime program Parker Spitzer, which she had been co-hosting with former New York Governor Eliot Spitzer. Starting on Monday, the program will be renamed In The Arena, and will feature Spitzer, as well as several others within and outside CNN, according to a memo by CNN U.S. chief Ken Jautz. Parker is expected to continue to make occasional appearances on the cable news network. Ratings for Parker Spitzer have been minuscule since its October launch but went up while Parker was on a sick leave recently and Spitzer was the sole anchor. The show was also plagued by constant rumors about friction between the two hosts. “It has been a joy working with (Parker) as a teammate, and I continue to be a huge fan of the wisdom that jumps from her written work and the wit, charm and insight she brings to all that she does,” Spitzer said in a statement.
