It's a victory for the mayor who says the new museum benefits inner-city kids.
Museum officials believe the $100 million renovation of the Field House will be a good addition to the park. But the local aldermen and preservationists argue moving the museum to the north end of Grant Park violates rules against building on park land.
Local aldermen who are against the plan are vowing to fight it.
"I think we got a decent shot beyond the zoning committee. I think this will be a very close vote by the city council and I think, to be honest, the public opposition to this is where the real momentum is," said Alderman Brendan Reilly, 42nd Ward.
The city council zoning committee will take up the issue next week. If they approve the plan, the entire city council will vote on it next month.
Opponents say they will take legal action to stop the move.
