Bob Vylan's career may be in trouble following their controversial performance at Glastonbury, experts tell Newsweek. Over the weekend, the English punk rap duo sparked outrage at the music festival in the United Kingdom. During their set, they led crowds in a chant of "death, death to the IDF," referring to the Israeli Defense Forces.

The BBC has issued a formal apology over Bob Vylan's controversial Glastonbury performance, claiming the London alt-rap duo was deemed "high risk."

The prime minister is involved; so is the U.S. deputy secretary of State. The BBC is changing policies. But Bob Vylan remains steadfast.
