Chicago Teachers Union Head Drops Out of Mayoral Race

Is battling a brain tumor

Chicago Teachers Union President Karen Lewis is expected to begin chemotherapy and radiation treatment next week for a brain tumor.

An ABC7 Eyewitness News source confirms the Chicago Sun-Times report that Lewis will not run for mayor because of the tumor. The 61-year-old underwent a five-hour surgery at Northwestern Memorial Hospital on Oct. 5, the source said.

Lewis was considered to be an early front runner in the race for Chicago mayor. Her exploratory committee announced her decision to pull out of the race on Monday.
