Donald Trump has agreed to sit for a victim interview with the FBI, which is investigating this month’s attempted assassination, an agency official said on July 29, Ednews informs referring to CNN.

Victim interviews are a routine part of criminal investigations, but are voluntary.

“The interview of the former president will be consistent with any other victim interview that we do,” Kevin Rojek, the special agent in charge of the FBI’s Pittsburgh Field Office, told reporters on a conference call Monday. The FBI wants to “get his perspective on what he observed, just like any other witness to the crime.”

“It is a standard victim interview, like we would do for any other victim of crime under any other circumstances,” Rojek said.

FBI investigators continue to focus their efforts on uncovering the motive of the 20-year-old would-be assassin, Thomas Matthew Crooks.

Crooks was “highly intelligent” and had a growing interest in shooting, Rojek said. While officials had already revealed that he searched “how far away was Oswald from Kennedy” before the shooting, Rojek said Monday that he also made searches related to “power plants, mass shooting events, information on improvised explosive devices and the attempted assassination of the Slovakian Prime Minister earlier this year.”

His primary social circle “appears to be limited to his immediate family, as we believe, he had few friends and acquaintances throughout his life,” Rojek said.

“While the FBI investigation may not yet have determined a motive, we believe the subject made significant efforts to conceal his activities,” Rojek said. “Additionally, we believe his actions also show careful planning ahead of the campaign rally.”
