WASHINGTON (AP) — Utah Gov. Spencer Cox said Sunday that investigators are not ready to discuss the motive behind the assassination of conservative activist Charlie Kirk. But he said the suspect had left-leaning political beliefs, disliked the conservative influencer and is being uncooperative in custody.

Cox said Tyler Robinson, 22, is “not cooperating” and that friends paint a picture of someone radicalized in the dark corners of the internet. “Clearly there was a lot of gaming going on,” Cox said on NBC. “Friends have confirmed that there was kind of that deep, dark internet, the Reddit culture, and these other dark places of the internet where this person was going deep.”

A Republican who has called on all partisans to tone down their rhetoric following the attack, the governor added: “I really don’t have a dog in this fight. If this was a radicalized MAGA person, I’d be saying that as well.”

The governor said the suspect’s partner was transgender, which some politicians have pointed to as a sign Robinson was targeting Kirk for his anti-trans views. But authorities have not said whether it is relevant as they investigate Robinson’s motive.
