Ted Koppel may be making a U-turn back to his 'This Week' anchor chair now that host George Stephanopoulos is tied up in his 'Good Morning America' role. Politico.com is reporting that Koppel may take the reigns of 'Week' three Sundays each month. Citing "broadcast industry sources," the Politico report states that no official offers have been made to Koppel just yet, but that a handful of kinks would need to be worked out before that could happen. The fourth Sunday of each month would be hosted by potential candidates for a full-time role in the future.
