The FBI used Israeli technology to hack into the cellphone of would-be Donald Trump assassin, Thomas Matthew Crooks, the Washington Post reported Tuesday.

After Crooks shot and killed one man and injured three, including grazing the former president’s ear, during a Saturday outdoor campaign rally, a Secret Service sniper shot him dead.

The report cited unnamed people involved in the investigation as saying that when a cellphone was found on the body it was taken to the nearby Pittsburgh FBI office, where the agents couldn’t break into it.
