WASHINGTON
US President Donald Trump said Monday that the suspect accused of killing conservative American activist Charlie Kirk was radicalized online, blaming left-wing extremism for the attack.
"I can tell you he didn't work alone on the internet, because it seems that he became radicalized on the internet," Trump told reporters. "That's just by watching the same things that you're watching and hearing."
Trump described the suspect as someone with "wonderful parents" who lived in a "wonderful neighborhood" and was a "smart guy, great marks, great student." But he said "something happened to him over a fairly short period of time."
"It looks like he was radicalized over the internet, and it's radicalized on the left," Trump continued.
Kirk was fatally shot last week while speaking during an event at Utah Valley University in Orem, Utah.
A suspect, 22-year-old Tyler Robinson, was arrested shortly after the attack.
FBI Co-Deputy Director Dan Bongino said Monday that Robinson had an “obsession” with Kirk and tracked his appearances online, though investigators have not established a motive.
