Newsweek: McCain camp and its Alaska allies move to shut down trooper-gate probe. Definitely take a look at the Newsweek article. Also take note of the following, that we're going to be looking into next week. Within days of Palin's selection, at least seven of her aides and associates, who had previously agreed to cooperate with the trooper-gate investigation, informed investigator Steve Branchflower that they were now no longer willing to be deposed. Note too that this was immediately after the McCain team deployed what George Stephanopoulos reported was a "rapid response team of about ten operatives that includes lawyers" to the state. So the question is: what contact did representatives of the McCain campaign have with these aides that had agreed to testify but within days of her selection took back their pledge and are now refusing to cooperate?

Stonewalling, arm twisting and intimidation?
