The McCain campaign is going to hold a press conference in Anchorage this afternoon concerning the “Troopergate” — Team McCain prefers to call it “Tasergate” — investigation. Word is the campaign is going to announce greater cooperation with the state personnel board probe, meaning that the Palin administration will provide documents and other evidence to the board. Sarah Palin’s attorney met yesterday with board investigators to discuss sharing documents and scheduling witness interviews — but there’s no word on whether Palin herself will be one of those witnesses.
