"When the mayor asked the host committee to release their fund-raising numbers, he was told . . . that early reporting of donors, who have been promised their support would not be reported until the FEC filing, could negatively impact the final weeks of fund-raising," Lauren Hitt, spokeswoman for Kenney, said Thursday. "So while, from a transparency standpoint, the mayor would like the records to be released, from a fiscal standpoint, he also doesn't want to do anything that could burden the taxpayer."
