 The work that's going on right now, the fairground where the rally took place, is a crime scene. So FBI officials are collecting evidence there. Special agents, of course, are conducting interviews. They're running down leads, including on tips that they're getting from the public. The FBI is still asking for more tips from the public. And then you have technical specialists, of course, who are also looking at digital evidence, whether it may be videos or whatnot that were taken the day of the rally.
