Chicago Mayor Rahm Emanuel said tonight that the city would file an injunction in circuit court "immediately" to halt the Chicago Teachers Union strike.

CTU President Karen Lewis indicated earlier today that the strike would continue for at least two more days, with the CTU House of Delegates slated to vote on a contract Tuesday. The House of Delegates met this afternoon and were expected to back a new proposal that is supported by Lewis. But, according to the Chicago Tribune, Lewis said delegates "are not happy with the agreement" and would like more time.

The mayor was unsparing tonight in expressing his agitation with CTU. "I will not stand by while the children of Chicago are played as pawns in an internal dispute within a union," Emanuel said in a statement. "This was a strike of choice and is now a delay of choice that is wrong for our children."
