Utah Governor Spencer Cox confirmed Charlie Kirk's alleged assassin is in a romantic relationship with a transgender lover.

Tyler Robinson, 22, was arrested Friday in connection to the murder that left the conservative activist dead after being shot in the neck at Utah Valley University.

Since his arrest, reports have swirled that Robinson was in a relationship with his roommate Lance Twiggs.

During a Sunday morning interview with CNN's Dana Bash, Cox confirmed Robinson's roommate was his 'romantic partner' and that it is being probed as a possible motive into Kirk's death.

'Yes, definitely. And yes, I can confirm that. I know that has been reported and that the FBI has confirmed that as well, that the roommate was a romantic partner, a male transitioning to female,' the governor said.
