(CNN) - Sources close to Sarah Palin told CNN Wednesday that the former Alaska governor is no longer likely to attend a tea party rally in Iowa on Saturday, an event that's been plagued by logistical issues.
Palin will still make a separate appearance in Des Moines on Friday to meet with her supporters.
The sources stressed that Palin does not want to disappoint her backers in the state who have been eagerly awaiting her appearance.
Saturday's "Restoring America Event" in Indianola had been hotly anticipated, given Palin's fast-approaching self-imposed deadline for making a decision about whether to run for president.
She has pointed to late September as a time frame for that decision. Late Tuesday, news broke that Palin will travel to the lead off primary state of New Hampshire on Monday for another tea party rally.
Palin herself has indicated that she did not plan to announce her political intentions on Saturday in Iowa, but supporters from around the country had already booked plane and bus tickets to the state to attend.
The Palin sources cited "issues with the planning" of the rally, which is being sponsored by Tea Party of America, a recently created group that has never put on a large-scale event.
Event organizers were caught in an embarrassing mix-up on Tuesday when they dis-invited, then re-invited, former Delaware Senate candidate Christine O'Donnell to speak at the event.
The Palin sources said event organizers had been "dishonest" about the speaking program and how the rally was being promoted.
They said Palin could still appear at the event.
