In the ethics investigation against her where she tried to have her sister's ex-husband ruined TPMMuckraker | Talking Points Memo | Palin Likely to Testify Soon, Under Oath, in Trooper-Gate Probe Palin Likely to Testify Soon, Under Oath, in Trooper-Gate Probe By Zachary Roth - September 1, 2008, 2:10PM It looks like the special investigator in the Trooper-Gate case -- in which John McCain's surprise VP pick Sarah Palin stands accused of trying to fire a state trooper who had been embroiled in a bitter divorce proceeding with Palin's sister -- could soon uncover exactly what happened. State Senator Hollis French, a Democrat and the chair of the bipartisan Senate committee overseeing the investigation, told TPMmuckraker that the independent investigator assigned to the case, Steve Branchflower, has contacted the Governor's office about having her deposed, and has received a response. French said that Palin's deposition would likely take place in the next few weeks and will almost certainly be under oath. "I think that's best," he said. Hollis added that Branchflower does not expect to have to subpoena Palin, as her office has been cooperative thus far.
