During an interview with NBC News aired on Wednesday's edition of MSNBC's "Andrea Mitchell Reports," Secretary of State Antony Blinken said Iran's Islamic Revolutionary Guards Corps (IRGC) is a terrorist organization, but responded to a question on whether they'll remain one under a revival of the Iran nuclear deal by saying that he didn't want to get into the details of talks. Blinken also stated that he isn't strongly optimistic that a new deal will be struck and that time to reach an agreement is running out.
