Utah governor says the motive in Kirk shooting is not yet certain but the suspect was on the left

“There clearly was a leftist ideology,” Cox said on NBC’s “Meet the Press,” citing interviews with Robinson’s relatives and acquaintances. “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.”

He pointed to references found engraved on the ammunition used to kill Kirk, which included anti-fascist and meme-culture language. Court records show that one bullet casing had the message, “Hey, fascist! Catch!”

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.”

Cox stressed on several Sunday morning news shows that investigators are still trying to pin down a motive for the attack on Kirk, a father of two and Trump confidant who was killed Wednesday while on one of his signature college speaking tours at Utah Valley University. The governor said more information may come out once Robinson appears in court Tuesday.

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

“The roommate was a romantic partner, a male transitioning to female,” Cox said. “I can say that he has been incredibly cooperative, this partner has been very cooperative, had no idea that this was happening.”

Investigators have spoken to Robinson’s relatives and carried out a search warrant at his family’s home in Washington, about 240 miles (390 kilometers) southwest of Utah Valley University, where the shooting took place.

State records show Robinson is registered to vote but not affiliated with a political party and is listed as inactive, meaning he did not vote in the two most recent general elections. His parents are registered Republicans.

Robinson grew up around St. George, in the southwestern corner of Utah between Las Vegas and natural landmarks including Bryce Canyon and Zion National Parks.

He became a member of The Church of Jesus Christ of Latter-day Saints, known widely as the Mormon church, at a young age, church spokesperson Doug Andersen said.

Online activity by Robinson’s mother reflects an active family that traveled widely. In one photo, a young Robinson can be seen smiling as he grips the handles of a .50-caliber heavy machine gun outside a military facility.

A high school honor roll student who scored in the 99th percentile nationally on standardized tests, he was admitted to Utah State University in 2021 on a prestigious academic scholarship, according to a video of him reading his acceptance letter that was posted to a family member’s social media account.

But he attended for only one semester, according to the university. He is currently enrolled as a third-year student in the electrical apprenticeship program at Dixie Technical College in St. George.

Meanwhile, Kirk was memorialized with candle-lit vigils and other events Sunday.

At Dream City Church in Phoenix, where Kirk hosted one of his “Freedom Night in America” gatherings, attendees viewed clips of the conservative activist discussing his desire to be “remembered for courage for my faith.”

During a question-and-answer session, a church pastor, Angel Barnett, called on the crowd to honor Kirk by carrying on his message.

“The left is nervous,” Barnett said. “And they’re concerned because they’ve lost control. Charlie started that, and we will continue it.”

Added church panelist Brandon Tatum: “These cowards thought that they could end or eliminate the movement.”

“They just made it bigger. They just made it stronger.”
