I don’t think he fabricated the woman. He made up some details and combined aspects of other relationships. But the actual woman does exist. A bit different here.
The book itself gave even more 'incredibility' inasmuch as Obama was praised for his writing talents and the stellar intelligence behind it; when of course; this was the 'voice and hand' of Bill Ayers. Te'o has yet to match the Lie of Obama.
That said; this is not about the authentically, inauthentic Obama. . .It is about a very big lie; or disturbed imagination of Te'o. James Frey was called to task by Oprah; for his 'blending' of facts. Obama; apparently and OTOH; never got the 'Oprah call'. Lance got his this week; so maybe Te'o will be next.
