Eleven U.S. senators have introduced a resolution backing the ongoing nuclear negotiations with Iran aimed at reaching a lasting agreement that prevents Iran from acquiring a nuclear weapon and opposing legislation to impose tougher sanctions.
The resolution -- by 10 Democrats and an Independent who caucuses with Democrats -- says the Senate is prepared to enact additional sanctions against Iran if current diplomatic efforts fail, but refuses to prejudge the outcome.
"Enacting new sanctions before the end of the negotiating period would gravely undermine our efforts to reach an agreement with Iran," Senator Dianne Feinstein (D-California), a leading co-sponsor of the resolution with Senator Chris Murphy (D-Connecticut), said in a statement.
U.S. President Barack Obama has vowed to veto a plan by some lawmakers to impose additional sanctions against Iran while nuclear negotiations are continuing.
