Palin's schedule has been the object of confusion for months.

WASHINGTON (CNN) – Despite an earlier announcement from a California Republican women's group, former Alaska Governor Sarah Palin will not be speaking to an event sponsored by the group scheduled for next weekend at the Ronald Reagan Presidential Library, a spokeswoman for her political action committee said Thursday night - the latest such high-profile incident of confusion over the governor's schedule over the past few months.

“As repeatedly stated to several in the media over the last week, former Governor Sarah Palin is not committed to attend the Simi Valley Republican Women’s event at the Reagan Library and in fact is not attending the event,” read a statement from Meghan Stapleton that was posted on Palin‘s Facebook site.

“Neither the Governor’s state staff nor SarahPAC has ever committed to attending this event or speaking at this event, and even requested that the Governor's name be removed from the invitation several weeks ago.”

Stapleton said Palin “has other work and commitments to take care of at that time” but did not elaborate.

Palin has been plugged as a headliner at several major events - including the annual Conservative Political Action Conference, and a major GOP fundraiser in Washington this spring - after organizers of the events believed they had received assurances from her representatives, only to learn that either the former governor's aides in Alaska or her staff at SarahPAC had been unaware of the commitment. That set of advisors would then announce publicly that Palin had never planned to attend the event.

Palin eventually decided to attend the major April fundraiser after the initial confusion - although organizers did not learn her final decision until just a few hours before the event was slated to start.

A representative of the Republican Women of Simi Valley, which bills itself as a non-profit group of volunteers, told CNN she had no comment about Palin’s statement. When asked if she knew who from Palin’s staff had accepted the invitation, she again said she had no comment.

In a statement released earlier this month, the group said the Saturday August 8th event, meant to commemorate the group‘s anniversary, said Palin was one of several scheduled speakers and was “slated to attend.”

“Sarah Palin loves Alaska & she has roots in southern California and our organization is very supportive of the troops! Palin also has a huge following in California, mostly folks who pay tribute to the Reagan legacy,” said Pat Saraceno, hospitality chair for the group. “Most of us view Palin as a ‘Reaganesque figure.”
