Anger, anxiety at US Muslim travel ban - Moustafa Bayoumi

The reaction to the United States Supreme Court's ruling to uphold a travel ban on Muslim travellers has been met with a swift and furious reaction. Nationwide protests erupted in the wake of the ruling - with demonstrators converging in front of the courthouse to oppose the decision. Moustafa Bayoumi is a writer and professor of English at City University in New York and described the ruling as a "dagger in the heart of the first amendment principle of religious neutrality". He talks to Guyon Espiner.
