The Federal Bureau of Investigation (FBI) said in a media conference call on August 28 local time that the motive of the suspect in the "attempted assassination" of former President Trump remains unknown. It is reported that the FBI provided an update on the investigation of the attempted assassination that day. During the course of the investigation, they conducted nearly 1,000 interviews, issued numerous search warrants and dozens of subpoenas, and analyzed hundreds of hours of video footage. The FBI said that despite analyzing the suspect's online activities in the days before the shooting, it still did not help them confirm the "determined (crime) motive".
