Lawmakers hoped to unveil a final bill late Monday, with a House vote as early as Wednesday.

The measure would reconcile a bill the House passed last December and one the Senate backed in May. But several lawmakers are concerned that the legislation does not go far enough. They are pushing for a bill that labels Iran's energy sector a "zone of proliferation concern" which would effectively ban all business.

A draft version of the bill says it is the sense of Congress that Iran's energy sector be treated as a "zone of proliferation concern."
