Donald Trump warned that anyone “celebrating” the assassination of Charlie Kirk would face consequences, echoing remarks from Deputy Secretary of State Christopher Landau about taking action against foreign nationals who glorify violence. Kirk, 31, was fatally shot during an event at Utah Valley University, prompting bipartisan condemnation from figures including Joe Biden and Barack Obama.

Newsweek reported some users have already faced workplace discipline over celebratory posts. Trump told reporters the administration was “looking at names” and considering visa measures, adding, “That’s not right,” while characterizing those applauding the killing as “deranged.”

He focused blame on the political left, claiming agitators and flag-burners come from that side and saying left-leaning groups were already under investigation. Pressed on specifics, he said announcements would follow but offered no details.

Amid the fallout, a website reportedly began compiling posts and identities of people who appeared to celebrate Kirk’s death, aiming to “expose” them. The episode has intensified debates about political violence, speech online, and how far authorities—and private entities—should go in responding.
