The Obama administration tells Al-Monitor that it "strongly opposes" an Iran sanctions bill that is scheduled for an initial vote this week, setting the scene for the first of what promises to be a long list of showdowns over Iran policy in 2016.

The House Foreign Affairs Committee on Jan. 7 is set to mark up legislation from Rep. Steve Russell, R-Okla., that would restrict the administration's ability to lift sanctions on Iranian financial institutions as called for under the Iran deal. Administration officials say the bill is a transparent attempt to derail the Joint Comprehensive Plan of Action (JCPOA).

"We’re aware of this draft legislation, and as we have long said, we are opposed to any legislation that interferes with the implementation of the JCPOA," a senior administration official told Al-Monitor via email. "From what we have seen of this bill, it would interfere with the implementation of the JCPOA, and therefore, the administration strongly opposes it."

The bill would require the administration to certify that Iranian financial institutions have not knowingly helped fund Iran's Islamic Revolutionary Guard Corps, foreign terrorist organizations and several other entities before they can be removed from the Treasury Department's list of specifically designated nationals. The Iran deal requires that the United States cease its nuclear-related sanctions on those banks as part of its obligations under Annex II of the deal.
