Is she the toughest principal in America?

Robert Redford presents "Chicagoland," a series exploring the highly toxic fight over slashing the bloated budget of America's third biggest city.

The man in charge is someone who relishes a fight – Mayor Rahm Emanuel who, last year, closed 50 Chicago schools affecting 27,000 students, which was the largest school closure in American history, most of them in low-income black neighborhoods.

That decision led to the mayor being called, a "liar", a "classist", a "racist" and "The Murder Mayor."

OutFront: Liz Dozier, who appears on "Chicagoland," is the principal of Fenger High School, located in Roseland, one of the Chicago neighborhoods hit by the closures.
