Sen. Jeanne Shaheen says she will support the Iranian nuclear deal negotiated by President Barack Obama's administration when it comes to the Senate floor.
The deal calls on Iran to curb its nuclear capabilities in exchange for relief from economic sanctions.
Shaheen, a Democrat, says the deal is "the best available option" for preventing Iran from obtaining a nuclear weapon" and that there are no credible alternatives to curb Iran's nuclear ambitions that do not involve the military.
If the deal goes through, she says the United States' commitment to defending Israel will remain unshakeable. Israeli Prime Minister Benjamin Netanyahu is harshly critical of the deal.
New Hampshire's Republican senator, Kelly Ayotte, says the deal does not allow for robust enough inspection procedures to ensure Iran complies with the agreement.
