Iowa tea-party organizers made three changes at Palin staff's request

Crow said two of the requests were logistical details: Email a copy of the program today, and address concerns about back-stage security and who will be allowed in that area.

Asked about the third request, Crow said: “Can I let that remain private for now?”

Meanwhile, Crow telephoned staff for O’Donnell, a Delaware Republican who ran for the U.S. Senate, to say she can’t speak at Saturday’s event.

“We’re all friends and she’s not coming,” he said, referring to O’Donnell.
