Bono testifies before US Congress on violent extremism

U2 front man Bono has testified before a Senate appropriations sub-committee on the refugee crisis and violent extremism.

Before sitting at the witness table on Tuesday, Bono posed for photos with three members of Code Pink - which works to end US wars and militarism and support peace and human rights initiatives - who wore pink tiaras and held cardboard torches and signs reading Refugees Welcome.
