President Barack Obama is considering appointing a “czar” to oversee an emerging nuclear deal with Iran, Politico reported Wednesday. But some critics are questioning whether such an appointment will be able to ensure that a nuclear deal would be effective.

An Obama administration official confirmed that one option under consideration is having a point person serving as the lead coordinator for implementation and enforcement. Other possibilities include beefing up staffing and funding at existing agencies, which range from the Treasury Department to the intelligence services, said a former administration official also familiar with the discussions.

Mark Dubowitz, executive director of the Foundation for Defense of Democracies, questioned whether the effect of having a “czars” is real or illusory, noting that there’s a “perception of these special positions … that they haven’t worked, they’ve been a failure and they are used to try to create a perception of influence and of the U.S. government getting things done.”
