CHICAGO (AP) — Mayor Rahm Emanuel responded Saturday to widespread criticism of his plan to close 54 Chicago Public Schools, saying he wasn’t interested in doing what was politically easy and that the pain of the closings doesn’t compare to the anguish of “trapping” kids in failing schools.

“If we don’t make these changes, we haven’t lived up to our responsibility as adults to the children of the city of Chicago,” Emanuel said in his first public statements since Thursday’s announcement. “And I did not run for office to shirk my responsibility.”
