In Congress, a bipartisan resolution vowing U.S. retaliation won unanimous approval in the early hours today. The House of Representatives passed the nonbinding measure by a vote of 408 to zero about 12 hours after the Senate approved it 100 to zero. Arizona Senator John McCain, veteran of the Vietnam War, said the United States had a message for those behind the attacks. He said, “We’re coming after you. God may have mercy on you, but we won’t.”
