Chicago City Clerk and mayoral candidate Miguel del Valle joined parents and their backers to show his support Monday.
The parents have been sitting in as a show of civil disobedience. They are opposed to the demolition of the school's field house.
Del Valle promised to take action to resolve the issue.
"Until we strengthen our neighborhood schools, we're not going to see the kind of quality educational opportunities that every child in the system needs and certainly every child in the system deserves, and every child in the system has a right to receive," said del Valle.
Chicago Public Schools officials say the building is structurally unsound and needs to be torn down.
