The son of Ryan Routh (the guy who wanted to murder Trump) had hundreds of videos of child pornography in his house. As we read in Fox News:

he son of would-be Trump assassin Ryan Routh has been taken into custody on federal charges of possessing child pornography.

Authorities seized multiple electronic devices from 35-year-old Oran Alexander Routh’s home in Greensboro, North Carolina on Saturday that investigators say contained “hundreds” of files with child exploitation material. The illicit material was discovered during a search conducted “in connection with an investigation unrelated to child exploitation,” according to a criminal complaint.

Routh has been charged with receipt of child pornography and possession of child pornography.

The FBI conducted a search of Oran Routh’s home on Sept. 21 as part of the investigation into his father. Investigators confiscated several electronic devices, including a Samsung Galaxy Note 9 device. After authorities obtained a warrant to search the electronics, investigators discovered child pornography videos on an SD card located in the Samsung device.

“A review of the SD card located in Device-1 revealed that it contained hundreds of child pornography files,” the criminal complaint states. “These files include videos from a known child pornography series created outside the state of North Carolina.”

Investigators subsequently found a second device they say contained child pornography and described the content of those videos in graphic detail.
