Good luck, it will be impossible Poll: Most in NJ want Menendez to resign if found guilty MORE (D-N.J.) introduced amendment 3232, which would further tighten economic sanctions against Iran, just a year after Congress passed what some called extremely tough measures against Tehran.

Menendez said his amendment, which passed on a 94-0 vote, was needed because of new evidence from the International Atomic Energy Association indicating that Iran appears to be adding centrifuge capacity and conducting explosives tests that could be used to detonate a nuclear weapon.

"Our message is clear. The window is closing. The time for the waiting game is over," Menendez said on the Senate floor late Thursday.

"Yes, our sanctions are having a demonstrable effect on the Iranian economy, but Iran is still working just as hard to develop nuclear weapons."

Menendez’s amendment would sanction energy, port and shipbuilding sectors, particularly entities that supply certain commodities to Iran that are seen as contributing to Iran's shipbuilding capacity. These commodities include graphite, aluminum, coal, steel and software used to integrate industrial processes.

Another foreign policy amendment was introduced by Sen. Jeff SessionsJefferson (Jeff) Beauregard SessionsIntel leaders: Collusion still open part of investigation Republicans jockey for position on immigration Biden to Alabama: No more extremist senators MORE (R-Ala.). Amendment 3009 requires Congressional review of the bilateral status of forces agreement between the United States and Afghanistan for troop withdrawal. The measure passed on a voice-vote.

Sessions said that since the Islamic Republican of Afghanistan — their equivalent of Congress — votes on whether to approve the agreement, the least the Obama administration could do is allow the U.S. Congress to review the agreement before it takes place.

The Senate is scheduled to continue amendment work on the National Defense Authorization Act, S. 3254, on Friday, with hopes of finishing work by the end of the week. The defense bill funds U.S. military operation.
