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

Organizers of the Glastonbury Festival said Sunday they are "appalled" by the onstage statements of the punk duo Bob Vylan, whose singer led the crowd in a series of chants including "Death, death to the IDF" and "Free Palestine" the day before.

Deputy Secretary of State Christopher Landau confirmed the duo's visas have been revoked "in light of their hateful tirade at Glastonbury, including leading the crowd in death chants."
