“What @JohnKerry has done by engaging with #Iran’s regime, the world’s top state sponsor of terror, is unseemly, unprecedented, and inconsistent with U.S. foreign policy. The deal failed. Let it go,” Pompeo tweeted.

“#JCPOA didn’t stop all paths for #Iran to develop nuclear weapons, contrary to the way it was sold to the American people,” Pompeo added in a second message, referring to the Iran deal.
