As nuclear talks with Iran enter the final phase, candidates for the 2016 presidential elections in the United States are also being forced to clarify their position on this key issue.
Most Democratic candidates support the deal.
Republicans, however, are urging US President Barack Obama to walk away from the nuclear deal while he can.
Former secretary of state Hillary Clinton, who is considered the leading Democratic candidate for the 2016 presidential election, backed the president.
“I so hope that we are able to get a deal in the next week that puts a lid on Iran’s nuclear weapons program,” Ms Clinton told a rally in New Hampshire.
The new deadline for concluding a deal with Iran that prevents it from making a nuclear weapon expires on Tuesday.
Earlier, the US Senate had fixed June 30 as the deadline for the P5+1 countries – the United States, Russia, China, Britain, France and Germany – to conclude the deal. But last week, the two sides extended the deadline to July 7.
