I certainly won’t.’" He added, "I was kept out of meetings from that time forward."OBAMA OFFICIAL WHO BACKED IRAN DEAL SPARKS ONLINE OUTRAGE WITH REACTION TO TRUMP'S STRIKE: 'SIT THIS ONE OUT'Blair described the meeting as one that had been presented as an opportunity to provide input on Iran policy, and he made the "mistake" of thinking Obama was honestly looking for "fresh insights."Blair served as Obama's DNI from the start of his presidency in 2009 until he resigned at Obama's request in May 2010.Obama would go on to negotiate the Iran nuclear deal during his second term, which his administration hailed as a landmark diplomatic achievement that limited the country's nuclear ambitions while avoiding bloodshed.
