Draft legislation responding to U.S. President Donald Trump's refusal to certify the Iran nuclear deal would set tough new terms for the pact, including restoring sanctions if Iran tests a ballistic missile able to carry a warhead or bars nuclear inspectors from any sites, according to Reuters.
Critics of the legislation drafted by Republican Senators Bob Corker and Tom Cotton, with support from the Trump administration, said it could put the United States in violation of the international agreement if it were enacted.
The draft, seen by Reuters on Tuesday, was in the works on Oct. 13 when Trump announced he would not formally certify that Tehran was complying with the international nuclear pact, and called on Congress to write legislation to toughen it.
Since then, Corker has met with Senate Democratic colleagues, at least some of whom would have to back the legislation for it to pass. They have insisted that Washington work with European allies who co-signed the deal before making any changes.
Britain, France, Germany and the European Union, which also signed the nuclear accord - as did Russia and China - warned that Trump's plan could cause a split with Washington and risked U.S. credibility abroad.
Corker, chairman of the Senate Foreign Relations Committee, told Reuters last week that the Trump administration must work closely with European allies as it develops its new Iran policy.
The draft legislation, a proposed amendment to the Iran Nuclear Agreement Review Act passed in 2015, broadens a required administration assessment on whether Iran is complying with the pact to add factors related to issues from trade to whether Iran is using commercial aircraft licensed by the United States for non-civil aviation purposes.
