Good Tuesday morning. Situational awareness: The death of former U.Va. student Otto Warmbier puts the U.S. on the spot to confront North Korea over his coma. Polls open at 7 in Georgia for what the N.Y. Times' Jonathan Martin and Nate Cohn call "quite possibly the most consequential special election since Watergate." And Speaker Ryan gives a speech on "transformational tax-reform" in which he promises: "We are going to get this done in 2017."
