A video has surfaced showing Chicago Teachers Union President Karen Lewis on stage in front of a live audience, cracking jokes about U.S. Education Secretary Arne Duncan’s “lisp” and her marijuana-smoking days at Dartmouth College. Eddie Arruza has reaction on Chicago Tonight at 7:00 pm.

The video in question was taped on Oct. 1 in Seattle, Wash. at a Northwest Teaching for Social Justice conference. Watch Lewis in the video below.
