iranCitizens for a Nuclear Free Iran is using Rational 360 for media support as it plans a $20M ad effort to thwart President Obama's signature foreign policy achievement.

CNFI is the tax-exempt entity established by the American Israel Public Affairs Committee, the ardent Iran deal foe that relies on Rational 360 for PR.

Patrick Dorton, partner at the DC PA shop, told the New York Times CNFI would launch "a sizable and significant national campaign on the flaws in the Iran deal.”

Once Congress receives the Iran deal, it will have a 60-day window to review the Iran agreement.

Republicans are largely dead-set against the Iran package, which makes Democrats a key target for CNFI's campaign that is planned for 30 to 40 states.

Dorton, who served as media relations chief during Arthur Andersen's crisis, has strong Democratic ties.

He was special assistant to President Clinton, and press secretaries for former Sen. Tom Harkin (Iowa) and Congressman Peter DeFazio (Oregon).
