The chairman of the Senate Foreign Relations Committee has denied that partisan politics in Washington DC could derail America's landmark agreement to curb Iran's nuclear capabilities. Countering President Barack Obama's previous assertion, Senator Bob Corker, a Republican from Tennessee, said on Sunday that congressional oversight 'doesn't mean there won't be a deal'. The 62-year-old politician continued: 'We just set in place a process to ensure that if there's a deal, it's a deal that will stand the test of time, that will keep Iran from getting a nuclear weapon.' Making an appearance on Fox News Sunday, Corker  said that Congressional scrutiny and approval of any nuclear agreement with Iran is essential to help make sure that the deal is not a bad one. Scroll down for video . Chairman: Senator Bob Corker (pictured), of the Senate Foreign Relations Committee, has denied partisan politics in Washington DC could derail America's landmark agreement to curb Iran's nuclear capabilities . He said that Congress has a responsibility to scour the details of a final plan - including any classified annexes - and ask the Obama administration hard questions about it, before finally voting on it. 'It's very important that Congress is in the middle of this, understanding, teasing out, asking those important questions,' Corker said. Negotiators announced a framework deal on Thursday. The deal is scheduled to be finalized by June 30. Meanwhile, the Committee is due to meet April 14 to consider Corker's legislation to ensure that Congress debates and signs off on any pact. The bill requires the president to transmit, within five days of reaching a final deal, the text of the full agreement, along with materials related to its implementation. With key elements still to be finalized, the framework agreement sealed by U.S.-led world powers describes a program for stunting Iran's capacity to produce nuclear weapons, while giving Tehran quick access to assets and markets now blocked by international sanctions. In defending the framework and a potential final pact, US Energy Secretary Ernest Moniz cited what he called 'unprecedented access and transparency' into Iran's nuclear activities. Argument: Countering President Barack Obama's (pictured) previous assertion, Corker, a Republican from Tennessee, told Fox News Sunday that congressional oversight 'doesn't mean there won't be a deal' These will allow the U.S. and its partner negotiators to know almost instantly should Iran try to evade the oversight, Moniz said during an appearance on CBS' 'Face The Nation. This is a long-term arrangement, he stressed, with requirements lasting a quarter century or more. 'We'll have eyes on the entire supply chain of uranium,' he added on the program. 'Going back to mines, the mills, we'll have continuous surveillance of centrifuge production.' Israeli Prime Minister Benjamin Netanyahu has criticized the framework as deeply flawed and a threat to Israel's very existence. He is urging negotiators to improve the agreement or scuttle it. Other Republicans have echoed Netanyahu's concerns. Senator Lindsey Graham, a Republican from South Carolina, said on Sunday the proposed deal is a bad one - but was the best one Obama could get because the Iranians don't fear or respect him. Response: Israeli Prime Minister Benjamin Netanyahu (left) has criticized the framework deal as deeply flawed and a threat to Israel's very existence. But in defending the framework, US Energy Secretary Ernest Moniz (right) cited what he called 'unprecedented access and transparency' into Iran's nuclear activities . He said that he favors waiting until a new president, Democratic or Republican, takes office in January 2017 and then trying again. In the meantime, economic and financial sanctions would stay in place. 'Is there a better deal to be had? I think so,' Graham said on CBS' 'Face The Nation.' But a senior Senate Democrat, Dianne Feinstein, warned that bashing the proposed deal could backfire on Netanyahu. The Israeli prime minister and other critics of the framework agreement have offered no viable alternatives, she said on CNN's 'State of the Union.' Feinstein said imposing more and stiffer economic sanctions would only drive Iran's nuclear program deeper underground and make it more difficult to monitor. 'I wish he would contain himself,' Feinstein, the top Democrat on the Senate Intelligence Committee, said of Netanyahu. Officials (L-r) European Union High Representative for Foreign Affairs and Security Policy Federica Mogherini, Iranian Foreign Minister Javad Zarifat, and an unidentified Russian official, look on as British Foreign Secretary Philip Hammond shakes hands with Secretary of State John Kerry in Switzerland . The preliminary deal,  announced in Switzerland on Thursday, sees Iran agree to not build any new centrifuges for 15 years, and not enrich uranium at the previously secret Fordow site for 15 years. The country also agrees to reduce nuclear-material centrifuges from 19,000 to 6,104, let the IAEA store all the extra centrifuges, give IAEA inspectors access to its uranium mills for 25 years and rebuild heavy-water reactor at Arak so it can't produce weapons-grade plutonium. And it would not build any new heavy-water reactors for 15 years. In return, the West will give Iran relief from nuclear-related economic sanctions 'if it verifiably abides by its commitments', and lift 'all past UN Security Council resolutions on the Iran nuclear issue' as soon as Iran has completed all its promised 'nuclear-related actions'. America's sanctions on Iran relating to 'terrorism, human rights abuses, and ballistic missiles' will remain in place.

He claims congressional oversight 'doesn't mean there won't be a deal' Adds Congressional scrutiny is vital to make sure deal is not bad one . Congress must 'tease out and ask important questions' about the pact . Any nuclear agreement with Iran must also be approved, Corker says . The deal, announced Thursday, is scheduled to be finalized by June 30 . Senate Foreign Relations Committee is due to meet April 14 to consider Corker's legislation to ensure Congress debates and signs off any pact .
