Senate Republicans on the Biden Admin. attempting to revive the JCPOA 4 yrs ago:"The administration has thus far refused to commit to submit a new Iran deal to the Senate for ratification as a treaty, as per its constitutional obligation, or for review under statutory requirements that passed on a bipartisan basis in response to the 2015 deal. Additionally, despite earlier promises to the contrary, the administration has failed to adequately consult with Congress."(Craig Caplan)
