Lawmakers from both parties are skeptical that Iran will stick to a new nuclear deal. They're calling for Congress to prepare tougher economic penalties to impose on Tehran if the accord falls apart.
Iran has reached an agreement with the U.S. and five other world powers to pause its nuclear program for six months in exchange for an easing of sanctions.
But there's distrust of Iran among both Democrats and Republicans, leading to rare bipartisan support for having new sanctions ready to go.
House Foreign Affairs Committee Chairman Ed Royce, a California Republican, says Iranians "are capable of cheating." And the committee's top Democrat, Eliot Engel of New York, agrees, saying "I don't think we should trust them."
Senate Foreign Relations Committee Chairman Bob Menendez of New Jersey says he'll work with colleagues to have sanctions ready should Iran breach the interim agreement.
Rep. Mike Rogers, the Michigan Republican who chairs the House intelligence panel, says he fears the deal with Iran "just rewarded very bad and dangerous behavior."
