As the Morning Joe panel discusses NBC News White House correspondent Kristen Welker’s reporting that Secretary of Defense James Mattis has said the U.S. will not “seize” Iraqi oil, which deviates from President Donald Trump’s often stated desire to keep Iraqi oil, Morning Joe veteran columnist Mike Barnicle says: “General Mattis is absolutely correct. Taking the oil is a war crime. You shouldn’t confuse the first Marine division with Quantrill’s Raiders after the Civil War.” Listen here for more on Secretary Mattis and President Trump’s differing views on taking Iraqi oil.
