A widely shared social media post by Harvard Law professor emeritus Laurence Tribe that described the suspect in the assassination of conservative activist Charlie Kirk as "ultra‑MAGA" drew swift criticism after elements of the claim were contradicted by law enforcement accounts and disputed online.

Tribe reposted an Occupy Democrats thread on X that sought to characterize the suspect, identified by authorities as 22‑year‑old Tyler Robinson, as a right‑wing adherent and said the attribution undercut what the account called a GOP effort to "pin the blame for this tragedy on liberals." The post was flagged on social media as inaccurate and prompted public pushback from commentators who called the reporting unverified.

Senior FBI officials told Fox News Digital that Robinson was in a "romantic relationship" with a transgender partner and lived with that person in an apartment in Saint George, Utah. Those details, along with other public reporting, prompted social media users and some commentators to dispute early social‑media claims that Robinson acted as an "ultra‑MAGA" assailant.

Jeremy Carl, a senior fellow at the Claremont Institute and a frequent conservative commentator, called Tribe's reposting "pure" disinformation on X and said the account cited by Tribe was a "notorious fake news site." Occupy Democrats, which describes itself as a major Democratic social media organization, had attempted to build a profile of Robinson in the wake of the shooting that included descriptions of his family and political leanings.

Republican Utah Gov. Spencer Cox, speaking to reporters on Friday, described Kirk's killing at Utah Valley University as a "political assassination" and said a family member had turned Robinson in to authorities. Cox said the family member relayed that Robinson "had become more political in recent years." Booking photos of Robinson have been released by Utah authorities.

Investigators recovered a weapon and spent shell casings at the scene. Social‑media posts and some outlets highlighted etched messages found on casings, including phrases such as "Hey fascist! Catch!" and other inscriptions that Occupy Democrats sought to interpret as inconsistent with a right‑wing motive. The variety of inscriptions, some referencing cultural phrases or video games, was cited in online debate over whether the etchings revealed a clear political message.

Tribe, who taught at Harvard Law School for decades and is now the Carl M. Loeb University Professor Emeritus, served on President Joe Biden's Presidential Commission on the Supreme Court of the United States in 2021 and was named by President Barack Obama in 2010 as the first senior counselor for access to justice. Fox News Digital said it reached out to Tribe and Harvard for comment; neither responded immediately.

Kirk, founder of Turning Point USA, was shot while speaking at an event at Utah Valley University. Authorities have not publicly detailed a motive for the shooting. In the hours after the attack, lawmakers and commentators across the political spectrum warned about the risks of violent rhetoric, and debate intensified over how to discuss the incident without prematurely ascribing political motives.

Social media posts and partisan outlets on both sides have circulated competing narratives about Robinson's political beliefs and possible motivations. News organizations and law enforcement officials have urged caution and emphasized the need for verified information as the investigation continues. Prosecutors and investigators in Utah have not released a formal motive as of the most recent public statements.
