WASHINGTON - Congress is moving toward action on Iran this week that would stop short of any package of new economic penalties that might derail an interim nuclear agreement.

In the House, aides say Majority Leader Eric Cantor could introduce a nonbinding resolution as early as Wednesday evening spelling out suggested terms for any final nuclear deal with Iran.

In the Senate, aides say Majority Leader Harry Reid is talking about possible sanctions votes in January after lawmakers return from their break.

Secretary of State John Kerry is on Capitol Hill asking senators to hold off on any new penalties. He told House members the same thing Tuesday.

The aides spoke on condition of anonymity because they weren't authorized to publicly discuss the legislative maneuvering.
