Tyler Robinson, 22, is the suspect in the fatal shooting of conservative activist Charlie Kirk, confirmed by Trump.

Robinson allegedly admitted—or hinted—to a family friend that he was involved, prompting police action. Authorities said he had recently become more political and critical of Kirk.

Kirk, Turning Point USA co-founder and Trump ally, was shot at Utah Valley University during a campus event and later pronounced dead.

His killing sparked widespread condemnation from politicians and international leaders.
