uss john mccain should be hidden from view. >> reporter: acting defense secretary patrick shanahan says that directive was not carried out. and according to shanahan, the tarp seen in this report was put there for maintenance, not to cover the mccain name. it was removed before the president arrived. today, acting white house chief of staff mick mulvaney insisting neither he nor the president were aware of the request. >> the fact that some 23 or 24-year-old person on the advance team went to that site and said "oh, my goodness, there's the john mccain, we all know how the president feels about the former senator, maybe that's not the best backdrop, can somebody look into moving it." that's not an unreasonable thing to ask. >> seriously? >> it's not. >> reporter: the president, who has attacked john mccain for years, telling reporters this week, whoever gave the directive was doing him a favor. >> i am not a fan of john mccain. >> reporter: meghan mccain saying the attacks have caused more pain to the late senator's family. >> because the president is obsessed because he's never going to be a great man like he was. >> tara, the acting defense secretary saying he was not aware of the request, and would

have never authorized it. >> reporter: that's right, he says he didn't know about it, and still needs to gather information about it. but he had a chance to call cindy mccain. tom? >> thank you. next, exclusive reporting from inside iran, where u.s. sanctions are hammering the economy as tensions escalate. what iran's foreign minister told abc news. martha raddatz is in tehran. eporter: this is a country in pain. its people caught in the middle of a dangerous standoff. >> america and iran, they are two boys, small boys that are just arguing, fighting, and they don't know what is happening to their people. i mean especially my people. people are suffering. >> reporter: four years ago, iranians were celebrating the
