Can Europe convince Trump to stay in the Iran nuclear deal?

French President Emmanuel Macron is on what some have called "Operation Save the Iran Deal." On a visit to the U.S., Macron will try to convince President Trump that the deal is working and that it's better to confront Iran while its nuclear program is frozen. But Trump is vowing to pull out of the deal unless the U.S. and Europe can fix it to his specifications. Nick Schifrin joins Amna Nawaz.
