Why do you say this? Did the Today show NOT cover the Terri story in the way you found to your liking? From the small amount of time I saw the show they seemed to cover the story completely.
Katie is a committed liberal, as has been demonstrated in the course of the hundred or more reports I've posted at FR documenting the liberal bias that creeps, or leaps, into Today.
I think it's fair to say conclude that Katie is pro-choice and also supported the husband's side in the Schiavo matter.
That being said, I also think it's fair to point out the moral inconsistency of her position: her ostentatious display of concern for animal life and her indifference to innocent human life.
