FEDERAL COMMUNICATIONS COMMISSION WASHINGTON OFFICE OF THE CHAIRMAN June 16,2015 The Honorable Bill Nelson United States Senate 716 Hart Senate Office Building Washington, D.C. 20510 Dear Senator Nelson: Thank you for your letter urging an update to the Commission's rules and guidance concerning the adequate disclosure of the identity of an entity that buys commercial or political advertising time on television or radio. Your views are very important, and I appreciate your sharing them with me. Currently, the Commission is concentrating its resources on a proceeding to expand the online file requirements to cable operators, satellite TV providers, broadcast radio licensees, and satellite radio licensees. The expanded rules, if adopted, will bring sunlight to political advertising, ensuring that the public has access to the political files of all broadcasters and MVPDs, not just television broadcasters. In the meantime, the Commission will track all proposed legislation related to this issue, including the bill you introduced last month, S. 1260, the Sunshine in Sponsorship ID Act. Please let me know if I can be of any further assistance. Sincerely,
