Kelly Rindfleisch, one of Walker's former aides, asks Supreme Court to toss her conviction

MADISON -- One of Governor Scott Walker's former aides has asked the U.S. Supreme Court to toss out her conviction for campaigning on government time.

Kelly Rindfleisch served as Walker's deputy chief of staff when Walker was the Milwaukee County executive.

Prosecutors accused her of working on Walker's gubernatorial campaign and Republican Brett Davis' lieutenant government campaign out of her county office. She was convicted in 2012 of one felony count of misconduct in office.

She argued in a petition to the Supreme Court that the warrants used to seize her email messages were unconstitutionally broad. A state appeals court rejected a similar argument this past November.

The state Department of Justice is defending the appeal. A DOJ spokeswoman says the agency is reviewing the petition.
