Secretary of State Marco Rubio said a deal between the U.S. and Iran could take place on Monday, but Tehran cautioned that "no one can claim" that progress made "means an imminent agreement is about to be signed."
Speaking to reporters as he geared up to leave India following an official visit, Rubio said the Trump administration "thought we might have some news last night, maybe today" but said he "wouldn't read too much into it."
