U.S. to impose new sanctions on Iran as standoff deepens

President Trump plans to unveil new sanctions against Iran Monday, as the U.S. and Iran trade new threats of military action. The president said in an interview that aired Sunday "I'm not looking for war and if there is, it'll be obliteration like you've never seen before." The U.S. blames Iran for recent attacks on oil tankers in the Middle East, which Iran denies. Ben Tracy reports.
