Hundreds of Chicago teachers and their supporters are shutting down streets in downtown Chicago as part of a one-day strike over education funding.
The Chicago Teachers Union is holding a rally outside a state office building. The group then plans to march through downtown, disrupting traffic during rush hour.
Union President Karen Lewis says teachers are "united with people across this city and state to fight for them."
Chicago Public Schools CEO Forrest Claypool and Illinois' Republican governor, Bruce Rauner, say the strike is illegal. CPS is seeking to block the union from future similar actions.
The union says the strike - which shut down schools for nearly 400,000 students - is legal. Some other labor unions and groups affected by a state and local budget crisis are joining the rally.
