Former House speaker Newt Gingrich will replace Palin as the keynote speaker at a joint fundraising dinner held by the campaign committees of Senate and House Republicans.
The scheduling change follows a communications breakdown between Palin's political staff and her aides in Alaska that left the dinner's organizers unsure the Alaska governor would actually attend the Washington event.
Congressional Republicans announced earlier this month that Palin would deliver the keynote speech at the dinner, but the governor's staff in Alaska said the next day that the governor knew nothing about the speaking slot.
"I communicated with the governor directly and she did not know anything about it," a Palin aide told the Anchorage Daily News after the speech was announced. "I pointed out the [National Republican Senatorial Committee] press release and she was like, 'No.'"
The NRSC said at the time that aides at Palin's political action committee - SarahPAC - had agreed to attend the dinner, but that the governor's staff in Alaska had not been made aware.

Two weeks ago, a spokesman for Palin, Bill McAllister, told CNN the "the governor herself had not confirmed" the appearance and that the matter was "still under review." Aides to Palin did not respond to multiple e-mails sent over the last week asking if Palin would make the trip to Washington this summer.
UPDATE: NRSC spokesman Brian Walsh confirmed the switch.
"After initially confirming her attendance, Governor Palin's team informed the Committees that her gubernatorial responsibilities in Alaska prevented her from committing until the end of the legislative session," he said.
"We completely understand and respect Governor Palin's focus on her official state business; however, there is obviously an enormous amount of planning that goes into this annual event. For that reason, we invited and are honored to have former Speaker Newt Gingrich join us as our speaker at the 2009 Senate-House Dinner. As one of our Party's brightest minds and most energetic speakers, we are looking forward to having former Speaker Gingrich provide the keynote address on June 8."
UPDATE II: Ken Spain, a spokesman for the National Republican Congressional Committee, said the committee decided to "go in another direction."
“Speaker Gingrich is a leader and an influential voice within the Republican Party and we are thrilled to have him," he said.
UPDATE III: Palin's staff continued to deny that she had ever been scheduled to attend. "The Governor never confirmed her attendance at the event," said SarahPAC spokeswoman Meghan Stapleton. "She was honored to receive the invitation and asked to confirm her attendance at the end of the legislative session. Governor Palin is thrilled to hear that Newt Gingrich will address the audience as the Governor continues to focus on Alaska."
