Palin fired Monegan in July. It later emerged that Palin, her husband and several high-level staffers had contacted Monegan about state trooper Mike Wooten.
The campaign has released a series of e-mail messages detailing the frustration several Palin administration officials experienced in dealing with Monegan. The "last straw," the campaign said, was a trip Monegan planned to Washington in July to seek federal money for investigating and prosecuting sexual assault cases.
In a July 7 e-mail, John Katz, Palin's special counsel, noted two problems with the trip: The governor hadn't agreed the money should be sought, and the request was "out of sequence with our other appropriations requests and could put a strain on the evolving relationship between the governor and Sen. [Ted] Stevens."
But a travel authorization document signed by Palin Chief of Staff Mike Nizich on June 18 approved Monegan's trip to Washington for the purpose of meeting Sen. Lisa Murkowski (R-Alaska).
The document's existence was first reported by ABC News on Friday. Monegan told ABC that the travel authorization was explicitly to pursue funding for the anti-sexual-violence program, but the document does not give that as a reason for the trip.
Monegan did not immediately return a message left at his Anchorage home.
McCain spokesman Taylor Griffin said Friday that the travel authorization was for a routine trip.
"He was not authorized to lobby Congress," Griffin said.
