 As the FBI and Secret Service are still investigating a possible motive, we are learning more about the suspect. Reporter Megan Schiller has that. He was a registered Republican who previously made a small donation to a Democratic-aligned group, $15 donation at that. At this time, there are no links to any foreign terrorism. The shooter is not well known to law enforcement here in this area of Pittsburgh, and so far, no motive released by the FBI.
