The Biden administration's negotiating team have reportedly acknowledged in private that an agreement that would go beyond curtailing Iran’s nuclear program is no longer possible.

Politico cited multiple people familiar with classified Congress briefings on the subject that the two Iran-related motions passed in the Senate on Wednesday were a warning shot to the US team negotiating restoring the 2015 agreement with Tehran.

Although the motions were non-binding, the vote was seen as a test run of the bipartisan rebuke that would likely happen if Washington and Tehran clinch an agreement that does not address Iran’s non-nuclear activities and removes Iran’s Revolutionary Guard (IRGC) from the list of foreign terrorist organizations.

The measures -- that for the first time forced lawmakers to go on record about the key sticking points in the year-long negotiations in Vienna -- were also hailed as modest victory for Republicans who have been urging the Biden administration to walk away from the talks, now in limbo for weeks now.

The first vote on Wednesday was proposed by Senator Ted Cruz that called for maintaining terrorism-related sanctions on Iran’s Central Bank to limit Tehran’s cooperation for China, while the other – led by Senator James Lankford instructed Senate conferees to make sure that a House bill would include language that the Biden administration cannot remove the terror designation of the IRGC.
