Reps. Conyers, Lewis balk at Obama's position on Iran

Lewis said, "We've got enough wars," stressing the need for diplomacy.

Conyers said, "I want military options off the table."

Asked about sanctions against Iran, Conyers said he is concerned sanctions "might hurt the people (of Iran), not the government."

Meanwhile, House Foreign Affairs Committee Chairwoman Ileana Ros-Lehtinen's (R-Fla.) Iran sanctions bill has picked up 21 co-sponsors this week. The measure now has a total of 318 backers, and is scheduled to be marked up later this month.
