John Kerry actually said...

"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."

"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."

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

"Our goal is to conclude the major elements of the deal by the end of March and then to complete the technical details by June."
