Cancellations represent escalating government-wide campaign to suppress criticism of rightwing influencer

Civil liberties advocates are warning that the Trump administration’s decision to strip visas from at least six foreign nationals over social media posts about Charlie Kirk’s killing represents yet another example of dangerous government crackdowns on protected speech.

On Tuesday, the state department announced it was systematically identifying visa holders who “celebrated the heinous assassination of Charlie Kirk”, declaring in a social media statement that “the United States has no obligation to host foreigners who wish death on Americans”.

The visa cancellations represent an escalating government-wide campaign to suppress criticism of Kirk, who was killed last month. The administration cut visas for nationals from Argentina, South Africa, Mexico, Brazil, Germany and Paraguay.

“You can’t defend ‘our culture’ by eroding the very cornerstone of what America stands for: freedom of speech and thought,” Conor Fitzpatrick, an attorney at the Foundation for Individual Rights and Expression (Fire) said in a statement to the Guardian. “The Trump administration must stop punishing people for their opinions alone.”
