The British punk-rap duo Bob Vylan, who on Saturday led the crowd in chants of “Free, free Palestine” and “Death, death to IDF” during their Glastonbury Music Festival performance, may be denied entry to the US for their actions.

According to a senior US State Department official speaking to The Daily Wire, they are “already looking at revocation” of Bob Vylan’s visas ahead of a roughly 20-city tour through the United States, with performances planned in several major cities including Washington, DC.

“As a reminder, under the Trump administration, the US government will not issue visas to any foreigner who supports terrorists,” the official said.

The BBC, which broadcast the festival live, aired Bob Vylan’s performance without censorship but did not broadcast the performance of Irish hip hop group Kneecap, who also expressed pro-Palestinian messages live, citing editorial guidelines.

A BBC spokesperson described the comments made during Bob Vylan’s performance as “deeply offensive” and said the broadcaster has no plans to make the performance available on its iPlayer streaming platform.

While performing at the Glastonbury Music Festival, vocalist Bobby chanted “Free, free Palestine” “Death, death to the IDF” and said “Hell yeah, from the river to the sea, Palestine must be, will be, inshallah, it will be free” while on stage.

Following the performance, StopAntisemitism, a privately-funded American advocacy group, called for Bob Vylan to have their visas revoked ahead of their concerts in the United States for their Inertia Tour. They currently have concerts scheduled across more than a dozen major cities in the US.

“This antisemite must have his visa denied/rescinded - his hate is not welcome here,” StopAntisemitism wrote on X, referring to Bobby.
