Tea Party organizer 'had to cancel' Christine O'Donnell to get Palin to attend

DES MOINES -- Tea Party of America President Ken Crow told NBC News, "I had to cancel Ms. O'Donnell" after a conversation with Sarah Palin aides -- and is now hopeful Palin will attend the Saturday rally in Indianola.

He was told by Palin's team that he'd have a final answer shortly.

This comes after failed Delaware Senate candidate Christine O'Donnell was in, then out, then back in, and now indefinitely out. And Palin was in, then "on hold."

The group has spent about $100,000 on the event for Palin and are thus waiting "with baited breath" for an answer. An official press release will come out after Palin people give Crow final word.

NBC News has not received comment from Palin's team so far.
