WASILLA, Alaska - Alaska Gov. Sarah Palin abruptly announced Friday she is resigning from office at the end of the month, a shocking move that rattled the Republican party but left open the possibility she would seek a run for the White House in 2012.

And Pam Pryor, a spokeswoman for Palin's political action committee SarahPAC, said the group continues to accept donations on its Web site, with an uptick in funds after Palin's announcement.

In a hastily arranged news conference at her home in suburban Wasilla, Palin said she will formally step down July 26, and Lt. Gov. Sean Parnell will be inaugurated at the governor's picnic in Fairbanks.
