Just days after the election, Rahm Emanuel has lost a key aide.
Erwin used office resources when she was executive director of the Illinois Board of Higher Education while working on Barack Obama's presidential campaign, along with planning a trip to the 2008 Democratic National Convention and engaging in campaign fundraising activity while on the job, the newspaper reported. She paid a $4,000 fine and agreed to never work for the state again
Erwin told the Tribune that neither Emanuel nor his campaign knew about the ethics violation before Friday.
A Rahm spokesman told the newspaper that the incoming mayor will "continue to consult her public policy knowledge."
