(CNN) - Alaska Gov. Sarah Palin, facing a string of costly ethics complaints, formally unveiled a defense fund Friday to help pay her legal fees - now surging past the half-million dollar mark.
"For Alaskans, the time has come to end the siege on our government by political tricksters. Enough is enough. With the help of reform-minded advocates from across our nation, we will stand up for what is right," said a message on the Web site for the Alaska Fund Trust.
"Your maximum contribution of $150.00 will allow the Governor, her family, and her colleagues to retire their legal debt at no cost to Alaskans and reduce the incentive for mischief by her opponents. Together, we can help Governor Palin and future elected officials turn back the tide of overtly partisan and unnecessarily personal political attacks."
Kristan Cole, a Palin ally from Wasilla, will run the fund, which she described as "one of the most restrictive and transparent legal funds in history." The group said it plans to voluntarily release the names of donors and size of their contributions.
"We have created one of the most restrictive and transparent legal funds in history," Cole said. The group has created downloadable comparisons of the group's restrictions in comparisons with other recent political legal defense funds, including those for both Clintons and former Alaska Sen. Ted Stevens.
The former Republican vice presidential candidate continues to face a steady stream of new filings - the latest just this week, over whether she used PAC funds to travel to an anti-abortion event in Indiana.
Earlier this month, a Texas businessman launched a Web site to help defray the governor's legal costs, but Palin spokeswoman Meg Stapleton said then that the official legal defense fund could only accept money from her official fund, which had yet to launch, and encouraged Palin's supporters to direct their contributions there.
