When he led the Chicago school system, mayoral candidate Paul Vallas took actions that resulted in more than $1.5 billion being transferred out of the city’s budget-strapped public schools and to some of the wealthiest individuals and banks on the planet, a new report shows.

Now, Vallas is in an election runoff against Cook County Commissioner Brandon Johnson to lead the city of Chicago, with big support from wealthy investors and other corporate interests — including from executives at law firms and banks that benefited from the controversial financing methods Vallas used as CEO of Chicago Public Schools from 1995 to 2001.

With less than two weeks left before the April 4 election — which polls show is a tight race — Vallas has faced little scrutiny over his tenure as the Chicago Public Schools chief, even though he helped create a slow-moving financial disaster for America’s fourth-largest school system.
