(CNSNews.com) – Despite a legal obligation to allow Congress to review the Iran nuclear agreement for 60 days, the Obama administration will press ahead with a U.N. Security Council resolution enshrining the deal, likely within days.
“We will be introducing a U.N. Security Council resolution perhaps as early as next week,” a senior administration official told reporters in a background conference call from Vienna, hours after the final agreement known as the Joint Comprehensive Plan of Action (JCPOA) was announced.
The official said the resolution wording had already been drafted in Vienna, with the U.S. in the lead.
