The billionaire French donors that publicly promised flashy donations totaling hundreds of millions to restore 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 mainly American citizens that have footed the bills and paid salaries for the up to 150 workers employed by the cathedral since the April 15 fire.
