"As part of the JPOA we also committed, within the bounds of our system, not to impose new nuclear-related sanctions while the JPOA is in effect."

"Even if Iran does not walk away or promptly returns to the table, its negotiators are likely to adopt more extreme positions in response."

"Today, as the result of the constraints in the JPOA, Iran has halted progress on its nuclear program and it has rolled it back in key areas for the first time in a decade."

"Should Iran refuse a reasonable deal or cheat on its current commitments under the JPOA, the Senate and House could impose additional measures in a matter of hours."
