A senior University of Pennsylvania administrator faced swift criticism from lawmakers and conservative commentators after reposting and writing contentious messages on X following the killing of conservative activist Charlie Kirk.
Michael E. Mann, director of the university's Center for Science, Sustainability & the Media, deleted at least one post that said "the white on white violence has gotten out of hand," and retweeted multiple posts that mocked or criticized Mr. Kirk and a New York Times column about him. The reposts included a message that described Mr. Kirk with inflammatory language and another that labeled a column praising Kirk as "whitewashing" his legacy, according to screenshots and public reaction.
The posts drew sharp condemnation from Republican Sen. Dave McCormick of Pennsylvania and other conservative figures, who called the reposts "despicable" and urged the university to take decisive action. McCormick wrote that such rhetoric was unacceptable and demanded that the university respond. Other critics, including the executive director of Consumers’ Research and GOP communications officials, said the posts were inflammatory and argued Mann should be dismissed. Conservative commentator Steve Guest described the reposts as "absolutely ghoulish content."
Mann attempted to clarify his actions the following day, saying he had reposted material to register disagreement with a column by Ezra Klein and did not approve of the "inappropriate & inflammatory language" in some posts he had shared. He said he had deleted the reposts he found objectionable. In a separate message, Mann said he hoped "they catch him" in reference to the suspect in the Kirk shooting and wrote that political violence is unacceptable regardless of political affiliation.
The controversy follows an outpouring of public reaction after Kirk's killing, which included tributes and widespread commentary across media and social platforms. Mr. Kirk had previously warned of what he described as an "assassination culture" on the left prior to his death, comments that have since been reiterated in coverage and political discussion.
Critics of Mann also pointed to his public profile and past connections with Democratic figures. They noted Mann has testified before Congress, been involved in climate-policy discussions praised by prominent Democrats and appeared at events associated with Democratic-aligned groups, arguing he is not a private or apolitical account but a figure with institutional influence.
Mann’s posts included a link to Everytown, a gun control advocacy organization, in a comment about Utah Gov. Spencer Cox's response to the shooting. The governor was mentioned by Mann in the context of "thoughts and prayers" remarks at a press conference and prior legislation he had signed, according to the reposted link.
The University of Pennsylvania, Mann and his public relations representative were contacted for comment, according to the reporting outlet. The university has not publicly announced personnel action related to the posts.
The episode illustrates tensions that can arise when university-affiliated figures engage in polarizing public discourse about high-profile political violence. Advocates on both sides have used the episode to argue broader points about rhetoric, accountability and the responsibilities of public scholars.
Conservative commentators framed the reposts as an example of what they say is a permissive climate for demeaning political opponents, while defenders of Mann and other critics of Mr. Kirk argue that scrutiny of public figures and their rhetoric is part of public debate. No criminal or civil proceedings have been announced in connection with the posts themselves.
Fox News Digital reported reaching out to the university and Mann for comment. The coverage of the posts comes as debate continues in political and media circles over how institutions should respond when employees or affiliates make controversial statements online in the wake of violent incidents.
