LANSING, Mich. (AP) — The attorneys general of Michigan and Oklahoma are urging leaders in every state to impose state-based sanctions against Iran in response to a nuclear accord between Iran, the U.S. and other nations.

Michigan Attorney General Bill Schuette and Oklahoma Attorney General Scott Pruitt and sent a letter Monday encouraging sanctions to prohibit the investment of state assets in Iran.

The U.S. negotiated alongside other nations for nearly two years before finalizing an accord to curb Iran’s nuclear program in exchange for billions of dollars in sanctions relief.

But the letter says the agreement is a bad deal that requires only marginal changes to Iran’s nuclear program while allowing Iran to maintain technology that would lead to a nuclear weapon.

The letter says 25 states have already enacted sanctions against Iran.
