Sept. 16 (UPI) -- The State Department is revoking the visas of non-citizens in the United States "celebrating" the shooting death of conservative provocateur and activist Charlie Kirk, Secretary of State Marco Rubio said.

Secretary of State Marco Rubio announced the visa revocations were "under way" on X on Monday, in a post accompanied by a clip from a Fox News interview in which he said, "We are not in the business of inviting people to visit our country who are going to be involved in negative and destructive behavior."

"America will not host foreigners who celebrate the death of our fellow citizens," Rubio said on X.

Kirk, a divisive far-right figure and Trump ally, was fatally shot on Wednesday during a speaking event at a Utah university. Since then, the Trump administration and conservatives have condemned those who have criticized Kirk online following his death.

A day after Kirk's death, Deputy Secretary of State Christopher Landau called on the public to report to the State Department any non-citizens "praising, rationalizing or making light of the event" on social media.

Trump, who has blamed his death on the "radical left," has vowed to target those he sees as bolstering political violence, including organizations that allegedly fund and support it.

Vice President JD Vance on Monday during an episode of Kirk's podcast filmed at the White House called on the public to report those who were "celebrating" the provocateur's death.

"Call them out, and hell, call their employer," he said. "We don't believe in political violence but we do believe in civility. And there is no civility in the celebration of political assassination."

The Trump administration has revoked visas over social media comments in support of Palestine amid Israel's war against Hamas in Gaza.

The State Department in June announced that its overseas visa application process would include social media vetting.
