In April 2018, former Secretary of State John Kerry met with the Iranian Foreign Minister in order to ensure the Iran nuclear deal framework remained more or less intact. Matthew Summers, a spokesman for Kerry, admitted that Kerry "urged Iran to keep its commitments under the Iran nuclear agreement". Stephen Vladeck, law professor at the University of Texas, did not agree that Kerry would be in violation of the act as his intent was to preserve the US policy then in place, rather than seeking to destroy it. Vladeck has also said of the Act: "It raises serious constitutional questions that I think would dissuade even the most zealous prosecutor from trying a case under the Logan Act.”
