Sen. Chris Murphy (D-Conn.) is calling on Congress to follow the footsteps of the United Kingdom, which is preparing to officially authorize military action against the Islamic State in Iraq and Syria (ISIS). As the one of the nation’s closest allies prepares to debate and vote on their involvement, Murphy said it’s well past time the U.S. do the same. “Congress must declare war against ISIS,” he said. “Each one of us first ran for office on the promise that we wouldn’t shy away from tough debates, but rather, would rise to the challenge the times demand. Now is the time to prove we meant it.”
