When Palin released her family's tax records as part of her vice presidential campaign, some tax experts questioned why she did not report the children's state travel reimbursements as income.

The Palins released a review by a Washington attorney who said state law allows the children's travel expenses to be reimbursed and not taxed when they conduct official state business.

Taylor Griffin, a McCain-Palin campaign spokesman, said Palin followed state policy allowing governors to charge for their children's travel. He said the governor's office has invitations requesting the family to attend some events, but he said he did not have them to provide.

In October 2007, Palin brought daughter Bristol along on a trip to New York for a women's leadership conference. Plane tickets from Anchorage to La Guardia Airport for $1,385.11 were billed to the state, records show, and mother and daughter shared a room for four nights at the $707.29-per-night Essex House hotel, which overlooks Central Park.

The event's organizers said Palin asked if she could bring her daughter.

Alexis Gelber, who organized Newsweek's Third Annual Women & Leadership Conference, said she does not know how Bristol ended up attending. Gelber said invitees usually attend alone, but some ask if they can bring a relative or friend.

Griffin, the campaign spokesman, said he believes someone with the event personally sent an e-mail to Bristol inviting her, but he did not have it to provide. Records show Palin also met with Mayor Michael Bloomberg and Goldman Sachs representatives and visited the New York Stock Exchange.

In January, the governor, Willow and Piper showed up at the Alaska Symphony of Seafood Buffet, an Anchorage gala to announce winners of an earlier seafood competition.

"She was just there," said James Browning, executive director of Alaska Fisheries Development Foundation, which runs the event. Griffin said the governor's office received an invitation that was not specifically addressed to anyone.

When Palin amended her children's expense reports, she listed a role for the two girls at the function — "to draw two separate raffle tickets."

In the original travel form, Palin listed a number of events that her children attended and said they were there "in official capacity helping." She did not identify any specific roles for the girls.

In July, the governor charged the state $2,741.26 to take Bristol and Piper to Philadelphia for a meeting of the National Governors Association. The girls had their own room for five nights at the Ritz-Carlton Hotel for $215.46 a night, expense records show.
