On Friday, Christiane Amanpour left CNN after 27 years at the network. As we noted in March, the cable news mainstay is set to pick up hosting duties for ABC's This Week later this summer taking over for ABC News' Jake Tapper who will continue to fill-in as host until Amanpour's transition is complete in August.

For his part, Tapper has partnered with PolitiFact.com to offer a weekly fact-check of This Week -- something other Sunday show hosts like NBC's David Gregory and CBS' Bob Schieffer have declined to do thus far instead leaving it up to their viewers.

Amanpour will be the only woman hosting one of the all-important Sunday morning network political talk shows -- an accomplishment to be sure. It remains to be seen however, if she will continue Tapper's trial partnership with PolitiFact.com. Should she continue such a partnership, and I'm hoping that she does, it will further distinguish This Week from its more reticent rivals.
