 And the top law enforcement agencies, the FBI and Secret Service, are asking tough questions of themselves this morning. And police continue to search the suspect's home and talk to family, friends, anyone who knew this guy. Authorities identified him, as we've been saying, that 20-year-old from Bethel Park, Pennsylvania, shot to death by a Secret Service sniper. The motive, as I said, still not officially known. He was a 2022 graduate.
