New details emerge in Trump assassination attempt investigation

After conducting more than 100 interviews, searching the suspect’s home and vehicle, and cracking into his cellphone, FBI investigators were still searching on Tuesday for the motive that led a 20-year-old Pennsylvania man to attempt to assassinate a former president.

As that investigation continued, officials with the FBI and the Department of Homeland Security warned late Monday about the potential for “follow-on” or “retaliatory” acts.

“We cannot rule out the possibility that some DVEs or other actors may attempt follow-on or retaliatory acts of violence in response to this assassination attempt,” the two agencies said in a joint bulletin, using an acronym for “Domestic Violent Extremism.”

A cellphone used by the alleged assailant, Thomas Matthew Crooks, was sent to Quantico, Virginia, where FBI technicians gained access to its contents, officials said Monday.
