Katharine Hamilton, who became chairwoman of the College of DuPage's Board of Trustees earlier this year, resigned suddenly from the position on Sunday, according to the Chicago Tribune.
Hamilton, who cited "personal reasons" behind her decision, was credited as one of the people who challenged corruption at the college, particularly during former President Robert Breuder's tenure. Last year, Hamilton was censured for publicly criticizing Breuder and other trustees. She was first elected to the board in 2013 but became chair in April.
The community college, which is the largest in the state, remains under federal and state investigations related to administrative spending. The college came under scrutiny after awarding a $763,000 severance package to Breuder.
