MILWAUKEE (WTAQ) - A former Milwaukee County aide to Governor Scott Walker conceded Thursday that there’s enough evidence to order a trial on four felony charges against her.

Kelly Rindfleisch waived a preliminary hearing on 4 counts of misconduct in public office. She’s scheduled to enter pleas on March 20th.

The 43-year-old Rindfleisch was Walker’s deputy chief of staff when he was the Milwaukee County executive.

She was accused of using her county work hours to raise money for Republican Brett Davis’s unsuccessful campaign for lieutenant governor in 2010. Davis is now the state’s Medicaid director.

Rindfleisch is one of four ex-Walker aides charged as the result of a John Doe investigation. That probe continues by the Milwaukee County district attorney’s office.
