ANCHORAGE, Alaska — Gov. Sarah Palin charged the state for her children to travel with her, including to events where they were not invited, and later amended expense reports to specify that they were on official business.

The charges included costs for hotel and commercial flights for three daughters to join Palin to watch their father in a snowmobile race, and a trip to New York, where the governor attended a five-hour conference and stayed with 17-year-old Bristol for five days and four nights in a luxury hotel.

In all, Palin has charged the state $21,012 for her three daughters' 64 one-way and 12 round-trip commercial flights since she took office in December 2006. In some other cases, she has charged the state for hotel rooms for the girls.

Alaska law does not specifically address expenses for a governor's children. The law allows for payment of expenses for anyone conducting official state business.

As governor, Palin justified having the state pay for the travel of her daughters — Bristol, 17; Willow, 14; and Piper, 7 — by noting on travel forms that the girls had been invited to attend or participate in events on the governor's schedule.

But some event organizers said they were surprised when the Palin children showed up uninvited, or said they agreed to a request by the governor to allow the children to attend.

Several other organizers said the children merely accompanied their mother and did not participate. The trips enabled Palin, whose main state office is in the capital of Juneau, to spend more time with her children.

"She said any event she can take her kids to is an event she tries to attend," said Jennifer McCarthy, who helped organize the June 2007 Family Day Celebration picnic in Ketchikan that Piper attended with her parents.

State Finance Director Kim Garnero told The Associated Press she has not reviewed the Palins' travel expense forms, so she could not say whether the daughters' travel would meet the definition of official business.

After Republican presidential nominee Sen. John McCain chose Palin his running mate and reporters asked for the records, Palin ordered changes to previously filed expense reports for her daughters' travel.

In the amended reports, Palin added phrases such as "First Family attending" and "First Family invited" to explain the girls' attendance.

"The governor said, 'I want the purpose and the reason for this travel to be clear,"' said Linda Perez, state director of administrative services.
