In an investigation after that attack on the Saudi oil refinery, a U.S. team on the ground in Saudi Arabia has been gathering what a U.S. official calls "compelling forensic evidence" from the remnants of the some 20 drones and nearly a dozen cruise missiles. They have recovered a nearly fully intact cruise missile. And they're closely examining an image from Saudi social media: that appears to be missile wreckage. Adding to building evidence the attack was carried out by Iran and not Houthi rebels from Yemen, General Joseph Dunford of the Joint Chiefs told a reporter in London that, “Without prejudging intelligence, this looked like a very complex, precise attack, not consistent with previous Houthi attacks. We can say that now - that this attack was not consistent with previous Houthi attacks.” And while President Trump said that he thinks Iran “would like to make a deal,” on Monday, on Tuesday, Iran's supreme leader countered saying, "There will be no negotiations at any level with the United States.” ABC's Elizabeth McLaughin joins Tony From the Pentagon.
