It's a done deal, yet opponents of the Iran nuclear agreement refuse to give in quietly. The dangers of a nuclear Iran are just too great.

US Senator Menendez is the second leading Democrat to announce his opposition to President Obama's nuclear deal with Iran.

Members of Congress are frustrated at the Obama administration's lack of transparency with regard to side agreements between the IAEA and Iran concerning nuclear inspections.

The Iran nuclear deal President Obama has approved now faces a 60-day review in Congress. Will Congress also approve it? Obama has already said he would veto any opposition to the deal.

Iran and the P5+1 powers remain far from a deal as the nuclear negotiations deadline looms. The US Senate will wait until after the deadline to consider its next steps regarding sanctions.

It is clear that the US-Israel relationship will only get more difficult in the 22 remaining months of Barack Obama's presidency.

By unveiling new legislation, Congress continues its attempt to prevent the Obama administration from finalizing a deal with Iran that would threaten the world.

As the deadline for a deal with Iran nears and as talks have yet to produce a diplomatic solution, the US Senate is preparing for the day after.
