“The FBI confiscated all files and documents related to my campaign including check copies from donations and checking account ledgers,” Warner wrote. “They also took all computers and back ups for the Campaign and my business. I will get the information to you as soon as the documents / computers are released.” Federal authorities have not indicated what they are investigating after showing up to search the homes and legislative offices of Warner, former GOP House Speaker Glen Casada, state Rep. Robin Smith and former Casada chief of staff Cade Cothren. Agents visited Warner’s business address as well. In addition, three legislative staffers were subject to the search early this month and placed on paid administrative leave. The searches took place at the legislative office building in downtown Nashville and other locations across the state.
