In response to Tuesday’s attacks in Brussels, Republican presidential candidate and Texas Senator Ted Cruz said, “We need to empower law enforcement to patrol and secure Muslim neighborhoods before they become radicalized.” Among those to criticize his comments was New York City Police Commissioner William Bratton.

Commissioner William Bratton: “I would remind the senator he lives in the United States of America. And the statements he made today is why he’s not going to become president of this country, because we don’t need a president that doesn’t respect the values that form the foundation of this country.”

Republican front-runner Donald Trump called for “closing up” U.S. borders and doubled down on his vow to bring back torture. Democratic candidate Hillary Clinton warned against insulting Muslim Americans in the wake of the attacks, while her rival, Vermont Senator Bernie Sanders, said the United States is fighting ISIS, not Islam.

Sen. Bernie Sanders: “We are fighting a terrorist organization, a barbaric organization that is killing innocent people. We are not fighting a religion.”
