The document, provided to BuzzFeed by a Democratic source who is privy to the negotiations, proposes a number of alterations to a package aimed at raising the pressure on Iran to abandon a nuclear program most American observers believe is aimed at building a weapon. The administration’s changes would include waiting 180 days for the sanctions to take effect, as opposed to the 90 days as passed by the Senate.

The bill as passed by the Senate would bar transactions with businesses owned by Iran’s government, which are on a Department of the Treasury list of “specially designated nationals,” or SDN’s. The administration wants to prevent this part from applying to any of these business entities that aren’t already flagged for terrorism, human rights abuses or proliferation. The administration also wants to remove sanctions from metal providers.
