On July 22, Breitbart News was the first to point out that the states have the power to block significant portions of the Iran deal, whether or not it passes Congress. That is because most states have enacted legislation divesting from Iran, and some, like New York, have even harsher legislation that prevents the state from doing business with the regime or with companies that do so. In an op-ed in Monday’s Wall Street Journal, constitutional lawyers David B. Rivkin and Lee A. Casey agree: the states are “free to impose their own Iran-related sanctions.”
