US President Barack Obama has secured enough support in the US Senate to ensure that the Iran nuclear deal will go into effect.
According to BBC, Democrat Barbara Mikulski of Maryland became the 34th senator to back the deal on Wednesday.
The US Congress could still oppose the deal, but Obama has now enough votes to override any resolution of disapproval.
He has said the deal cuts off "every pathway to a nuclear weapon" for Iran.
"No deal is perfect, especially one negotiated with the Iranian regime," sad Mikulski in a statement.
"I have concluded that this Joint Comprehensive Plan of Action is the best option available to block Iran from having a nuclear bomb. For these reasons, I will vote in favour of the deal."
US Secretary of State John Kerry is expected to speak soon about the deal.
