Palin attorney Thomas Van Flein said in an e-mail that information on who will be interviewed and when will be known on Tuesday. He said additional coordination meetings with the investigator, Anchorage attorney Timothy Petumenos, are likely.
After that, however, Petumenos wants to keep the progress of the investigation confidential and the campaign will not have any further comment, McCain spokesman Taylor Griffin said.
Both the Legislature and the personnel board have hired investigators in separate inquiries of whether Palin abused her power when she fired Public Safety Commissioner Walt Monegan this summer. Monegan refused to dismiss a state trooper who went through a bitter divorce with her sister before Palin's became governor.
Palin has refused to participate in the Legislature's investigation since becoming Sen. John McCain's running mate.
The other investigation is overseen by the state Personnel Board, a three-member panel appointed by the governor. Panel members can be fired by the governor for cause. Two members are holdovers from the previous governor and Palin reappointed the third.
One, Alfred Tamagni Sr., donated $400 to Palin's 2006 campaign. Petumenos has donated money to several Democratic candidates.
Separately, two Alaska Democrats said they may bring witness tampering allegations against the McCain-Palin campaign. The two state lawmakers, Rep. Les Gara and Sen. Bill Wielechowski, said they are evaluating Alaska's criminal code to see if it applies in what's become known as the Troopergate probe.
Griffin said the campaign has not advised any witnesses on how to respond to subpoenas.
