expenses of $23 million. The year after Obama left office was the first year the foundation lifted a cap on donations. While it lists its donors on its website, it no longer specifically links donors to exact amounts. While the Chicago city government has not promised that the foundation's endowment details will be disclosed publicly, its agreement with the foundation requires that the foundation may not proceed with construction of the center until the building endowment is secured.
