Following yesterday's vote on an amendment adding substantial sanctions against Russia to the bill, the Senate today voted to pass the bill, which was designed primarily to impose a number of new sanctions on Iran for "non-nuclear" moves that the Senate objects to. This too easily passed, with a 98-2 result.
The legislation was loudly endorsed by Israel lobbying group AIPAC, and Sen. Chuck Schumer (D – NY) also made clear the vote was all about Iran, saying it proved "bipartisan unity" in support of Israel that they were moving to punish Iran so overwhelmingly.
The lone dissenters on the bill were Sens. Rand Paul (R -KY) and Bernie Sanders (I – VT). Paul's vote was unsurprising, as he'd also opposed yesterday's amendment on adding Russia sanctions to the bill. Sen. Sanders insisted his concern was that the new sanctions against Iran would imperil the P5+1 nuclear deal with Iran.
