In Tuesday debate, House Foreign Affairs Committee Ranking Member Howard Berman (D-Calif.) said sanctions against Iran's central bank would deal an "unprecedented blow" to Iran's economy.

"This may cause short term difficulties for the world's oil market, and it may rankle some of our allies, but it is necessary, because stopping Iran's nuclear program is of paramount strategic importance, and we're running out of time," he said.

The other bill, H.R. 2105, is the Iran, North Korea, and Syria Nonproliferation Reform and Modernization Act, which provides for new sanctions against companies that transfer certain goods, services and technology to these countries.

This bill was approved in a 418-2 vote. Both sanctions bills needed a two-thirds majority vote, as they were considered under a suspension of the rules.

Members also approved two other non-controversial bills. The first, H.R. 3421, would give congressional medals of honor to the victims of the 9/11 attacks. This passed 416-0.

The second, H.R. 1264, names a courthouse in Tennessee, and passed 418-1.

Later in the evening, the House approved H.R. 2668 by voice vote, and debated H.R. 443 and S. 278.
