Former White House communications director Mike Dubke on Thursday criticized President Donald Trump for shifting from an initial unifying tone to what he called partisan and inflammatory rhetoric during an Oval Office-style address following the killing of right-wing activist Charlie Kirk.

Dubke, who served as communications director in Trump’s first term, told CNN the president’s remarks were “most disheartening” given they came just hours after the assassination in Utah. He urged caution and restraint, saying, “Then there was the turn toward the negativity, the heated rhetoric of Democrats, the reference to Republicans as being Nazis and all of that. As a communicator, stop after the two-and-a-half minutes.” Dubke added that one of the powers of the Oval Office in times of strife is to try to unify the country.

The White House shared a video clip of Trump’s remarks on Wednesday in which the president described Kirk as a “martyr for truth and freedom” and spoke of his Christian faith. Trump then pivoted to warnings about what he called “radical left political violence,” asserting it was “directly responsible for the terrorism that we’re seeing in our country today.” The address did not reference reported instances of political violence targeting Democrats.

Federal authorities identified a “person of interest” in the shooting and said the individual remained at large as of Thursday evening, according to the FBI. Law enforcement agencies are continuing to investigate the circumstances of Kirk’s death in Utah.

Dubke’s critique reflects concern among some communications professionals and former administration officials over the tone of presidential remarks in moments of national mourning or political violence. He framed his comments around the traditional role of the Oval Office to seek unity during crises, arguing the initial portion of Trump’s statement could have sufficed as a unifying message before the shift to partisan commentary.

The White House’s distribution of the video and the president’s characterization of Kirk as a martyr followed a fast-moving sequence of events and public reaction to the killing. The address and the subsequent commentary come amid heightened attention to political violence and rhetoric in the United States, with officials and commentators debating the impact of public statements by political leaders.

Trump’s remarks and Dubke’s critique underscore ongoing tensions within conservative circles and across the broader political landscape about messaging and leadership after politically charged incidents. Investigations into the shooting remain active, and federal authorities have not publicly confirmed any motive or linked the person of interest to broader political factions as of the latest update.
