On Wednesday, two top McCain campaign advisers said that the clothing purchases for Ms. Palin and her family were a particular source of outrage for them. As they portrayed it, Ms. Palin had been advised by Nicolle Wallace, a senior McCain aide, that she should buy three new suits for the Republican National Convention in St. Paul in September and three additional suits for the fall campaign. The budget for the clothes was anticipated to be from $20,000 to $25,000, the officials said.

Instead, in a public relations debacle undermining Ms. Palin’s image as an everywoman “hockey mom,” bills came in to the Republican National Committee for about $150,000, including charges of $75,062 at Neiman Marcus and $49,425 at Saks Fifth Avenue. The bills included clothing for Ms. Palin’s family and purchases of shoes, luggage and jewelry, the advisers said.

The advisers described the McCain campaign as incredulous about the shopping spree and said Republican National Committee lawyers were likely to go to Alaska to conduct an inventory and try to account for all that was spent.

Ms. Palin has defended her wardrobe as the idea of the Republican National Committee and said that she would give it back.

“Those clothes, they are not my property,” she said. “Just like the lighting and the staging and everything else that the R.N.C. purchased.”

Advisers in the McCain campaign, in suggesting that Palin advisers had been leaking damaging information about the McCain campaign to the news media, said they were particularly suspicious of Randy Scheunemann, Mr. McCain’s top foreign policy aide who had a central role in preparing Ms. Palin for the vice-presidential debate.

As a result, two senior members of the McCain campaign said on Wednesday that Mr. Scheunemann had been fired from the campaign in its final days. But Rick Davis, the McCain campaign manager, and Mr. Salter, one of Mr. McCain’s closest advisers, said Wednesday that Mr. Scheunemann had in fact not been dismissed. Mr. Scheunemann, who picked up the phone in his office at McCain campaign headquarters on Wednesday afternoon, responded that “anybody who says I was fired is either lying or delusional or a whack job.”
