Bono: 'Send Amy Schumer and Chris Rock to fight Islamic State' U2 frontman Bono brought his star power to Capitol Hill on Tuesday as he called on members of Congress to take swift action to deal with the global refugee crisis and violent extremism. Before a Senate subcommittee, one of Bono's suggestions was to use comedy to fight extremist groups. "It's like, you speak violence, you speak their language. But you laugh at them when they are goose-stepping down the street and it takes away their power," he said. "So I am suggesting that the Senate send in Amy Schumer and Chris Rock and Sacha Baron Cohen, thank you." Bono testified on the impact of violent extremism and the role of foreign aid CREDIT: PETE MAROVICH/BLOOMBERG Bono drew a bleak picture as he described the flood of people fleeing their homes in the Middle East, Asia and Africa. The human torrent threatens the very idea of European unity, he said, as he urged lawmakers to think of foreign aid as national security instead of charity. Wearing his trademark rose-tinted glasses, Bono said members of Congress need to confront an "existential threat" to Europe that hasn't been seen since the 1940s. Countries such as Poland and Hungary are moving to the right politically, a shift he described as a "hyper nationalism." Bono co-founded the One Campaign, an advocacy group that works to end poverty and preventable disease.
