The Iowa Family Policy Council asked Palin to speak at its Nov. 21 event and expressed optimism that she'd attend.
But in a statement released Friday, council spokesman Bryan English says the group knew it was a longshot because Palin would be in the midst of a book tour. Palin is releasing a memoir, "Going Rogue."
Council leaders say they were raising money to cover the costs of her appearance, prompting some to question whether she would be paid for a speech.
In the statement, English says Palin asked to speak before the group in the future and made clear she wouldn't accept money for her appearance.
