According to local Kentucky news station WNKY-TV, the FBI launched an investigation into the attack shortly after it happened. They believe the attack, which occurred Friday afternoon, was politically motivated.

The Daily Caller revealed Saturday evening that the assailant, 59-year-old Rene Boucher, is a registered Democrat whose Facebook page was riddled with posts voicing his opposition to President Donald Trump and the GOP.
