CHICAGO (CBS) -- A day after Mayor Brandon Johnson announced his entire hand-picked school board would resign, dozens of members of the City Council blasted the recent developments in an open letter. Following the announcement of the resignations, the 41aldermen wrote, "This is unprecedented and brings further instability to our school district."

All seven members of the board of education for Chicago Public Schools are resigning. Their expected resignations have paved the way for Mayor Brandon Johnson to appoint board members who agree with his goals.

Some alderpeople question whether Johnson can push through big policy priorities in Springfield and City Hall, including his upcoming budget.
