Organizers of the Republican National Convention in Cleveland next week have sent a letter to the billionaire couple Sheldon and Miriam Adelson requesting they help cover the $6 million necessary for the festivities next week. “Over the past couple months, negative publicity around our potential nominee resulted in a considerable number of pledges backing out from their commitments,” the letter says. The letter reveals that more than two dozen corporations and individuals have not followed through on $8.1 million in pledged donations.
