PARIS - The billionaire French donors who publicly promised flashy donations totaling hundreds of millions to rebuild Notre Dame have not yet paid a penny toward the restoration of the French national monument, according to church and business officials.

Instead, it's been mainly American citizens, via the charitable foundation Friends of Notre Dame, that have footed the bills and paid salaries for the up to 150 workers employed by the cathedral since the April 15 fire that devastated the cathedral's roof and caused its masterpiece spire to collapse.

"The big donors haven't paid. Not a cent," said Andre Finot, senior press official at Notre Dame. "They want to know what exactly their money is being spent on and if they agree to it before they hand it over, and not just to pay employees' salaries."
