Secretary of State Marco Rubio and CBS Host Margaret Brennan sparred over whether U.S. intelligence had found that Iran had ordered the development of a nuclear weapon, with Rubio dismissing Brennans question as "irrelevant."Brennan asked Rubio if the United States saw "intelligence that the Supreme Leader had ordered weaponization" of uraniam on Face the Nation Sunday. Rubio, who also serves as National Security Advisor, shot back at the CBS host, saying that whether Irans supreme leader ordered weaponization didnt matter, the regime was already pursing a nuclear weapon."Thats irrelevant. I see that question being asked in the media all the time. Thats an irrelevant question. They have everything they need to build a weapon," Rubio said.RUBIO DECLARES IRAN'S DAYS OF 'PLAYING THE WORLD' OVER AFTER TRUMP'S DECISIVE STRIKEThe CBS host countered that whether weaponization was ordered was the "key point" in U.S. intelligence assessments. Rubio denied that was the case, and claimed that he knew the subject "better" than Brennan."Why would you bury things in a mountain, 300 feet under the ground? Why would they have 60% enriched uranium? You don't need 60% enriched uranium. The only countries in the world that have uranium at 60% are countries that have nuclear weapons, because it can quickly make it 90. They have all the elements. Why do they have a space program? Is Iran going to go to the moon? No. They're trying to build an ICBM so they can one day put a warhead on it," Rubio responded.Brennan cited Director of National Intelligence Tulsi Gabbards March congressional testimony that Iran had not ordered the construction of a nuclear weapon. The "Face the Nation" host asked Rubio if the U.S. intelligence community had learned anything new since Gabbards testimony. Rubio accused Brennan of not presenting the assessment accurately.CLICK HERE FOR MORE COVERAGE OF MEDIA AND CULTURE"That's an inaccurate representation of it. That's not how intelligence is read. That's now how intelligence is used," Rubio said.Rubio went on to state that the International Atomic Energy Agency recently found Iran was not in compliance with its nuclear nonproliferation obligations. The IAEA report found that Iran could not account for how traces of uranium were found at undeclared nuclear sites."TheBoardof Governors... finds thatIran's many failures to uphold itsobligationssince 2019 to provide the Agency with full and timely cooperation regarding undeclared nuclear material and activities at multiple undeclared locations inIran... constitutesnon-compliance with itsobligationsunder its Safeguards Agreement with the Agency," the report said.CLICK HERE TO GET THE FOX NEWS APP"They have the delivery mechanisms, they have the enrichment capability, they have the highly enriched uranium that is stored. That's all we need to see. Especially in the hands of a regime that's already involved in terrorism and proxies and all kinds of things around. They are the source of all instability in the Middle East," Rubio said.
