The prosecution has rested its voter fraud case against Secretary of State Charlie White.White faces seven felony charges in Hamilton County, where he's accused of living in a Fishers condominium outside his town council district with his now current wife, but voting using an address where his ex-wife lived.Special Prosecutor Dan Sigler called his last witness Thursday morning, the fourth day of the trial.A representative from cellphone company Sprint testified that White made approximately five times as many calls from the vicinity of his ex-wife's house than from the vicinity of his current wife's house during the time period in question.The prosecution rested its case Thursday afternoon.The defense has indicated that it will not call any witnesses. White will not testify in his own defense.During jury selection, White's attorney, former Marion County Prosecutor Carl Brizzi, pointedly asked potential jurors if they would hold it against White if he did not call any witnesses. Any potential jurors who said they might, he reminded them, that according to the law, they could not.If convicted, White could face prison time and be forced to leave office.Democrats are already weighing in on who would take over the office, if White is convicted."We maintain that the Indiana Democrat Party has a judgement that is still there that has just been stayed that says Vop Oslii is the winner of the race for Secretary of State, the qualified candidate who actually won the race," said Karen Celestino-Horseman, the party's attorney. "We maintain he should be the one in office. Others may maintain the governor gets to make the selection."Closing arguments in the trial are scheduled for 9 a.m. Friday.
