The BBC issued a formal apology after broadcasting a controversial performance from the rap-punk group Bob Vylan at England's Glastonbury festival. Bob Vylan — outspoken critics of Israel's war on Gaza — led its crowd at last weekend's festival in a chant of "Death to the IDF," or Israel Defense Forces.

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