MILWAUKEE, Wis. (WHBL) - A former aide to Governor Scott Walker is scheduled to be sentenced next Wednesday, but that could be postponed. Darlene J. Wink has pleaded guilty to two charges of working on a political campaign while she was supposed to be doing her county job. Walker was Milwaukee County executive at the time. The prosecutor in Wink’s case says she will ask for a postponement so Wink can testify in another case. She could take the stand against Tim Russell, who is accused of stealing more than 21 thousand dollars from a non-profit organization he was running. Russell’s court date is December 3rd.
