Chicago Public Schools canceled classes for Wednesday after the Chicago Teachers Union's House of Delegates met to review the latest offer from the Chicago Public Schools and didn't vote on it.

Mayor Lori Lightfoot said the teachers union's bargaining team demanded "at the eleventh hour" that she support state legislation to elect rather than appoint the district's school board, as well as changes to state law governing what the union can strike over.

"Are we really keeping our kids out of class unless I agree to support the CTU's full political agenda wholesale?" Lightfoot said at a news conference. "If the CTU wants a deal, there's a deal to be had right now on the table."

During a second press conference hours later, Lightfoot said she met with the union's president and vice president during the day to present a sweetened offer, putting more money toward reducing class sizes and increasing long-time teachers' pay.
