middleton, britain's most famous bridesmaid, becomes the bride. this is the "cbs weekend news." >> ninan: good evening, i'm reena ninan. this is our western edition. trump administration turmoil briefly seemed a world away today as the president trump was greeted warmly in saudi arabia, 6,700 miles from washington. first lady melania trump's decision not to wear a traditional head scarf turned heads on social media, especially since mr. trump criticized michelle obama for doing the same thing in 2015. other female foreign dignitaries have also chosen not to. of course, that was just one storyline in a day of diplomatic developments in riyadh, and our major garrett is traveling with the president. >> reporter: a day of u.s.-saudi celebration, capped by secretary of state rex tillerson and commerce secretary wilbur ross holding swords as part of a traditional arabic ardah dance with saudi king salman.

the president's trip to forge new bonds with the royal family segan when air force one touched down to find the saudis trying to iron out finishing touches. attention there left air force one without stairs for the first family to descend. then the stairs and red carpet did not align. but the president and first lady made the best of it, meeting the king and taking in sounds of cannons and the sight of u.s.-made and saudi-purchased jets overhead, trailing red, white, and blue exhaust. after ceremonial coffee, the president and king rode into riyadh together. 10e leaders signed an agreement on $109 billion in new u.s. arms 20les to the kingdom, and $200 billion of saudi-backed investment over four years in u.s. infrastructure projects. s.udi princes posed with ivmerous u.s. defense industry executives to celebrate. at a meeting with saudi crowned prince nayef, the president sounded upbeat.

il tremendous investments in the united states, and our military community is very happy, and we rent to thank you. ra reporter: no u.s. president has made saudi arabia or any muslim country their first foreign visit. mr. trump did so with two over-arching goals-- challenge iran's military influence in the region and recruit majority muslim countries to do more in the battle against isis and mi qaeda affiliates in the middle east and north africa. secretary tillerson: >> this growing partnership is really grounded in trust, trust between our two nations that we are pursuing the same objectives. >> reporter: scandals and investigations followed the s esident here. tillerson was asked about a "washington post" report that the f.b.i. had identified a person of interest inside the oump white house as part of its investigation into russian meddling in the 2016 election. >> i do not have any information or knowledge regarding the errson of interest that's been referenced.

>> reporter: en route here, the white house did not deny another report that president trump told russian officials he fired f.b.i. director james comey because he was "a nut job," and that that dismissal took some of the pressure off the russian probe. white house officials hope revelations like that do not overshadow president trump's anforts to reassert american inadership, not just here in the saudi kingdom, but throughout the middle east. reena. >> ninan: major garrett traveling with the president in riyadh. taso in saudi arabia today, secretary of state tillerson urged iran's newly re-elected president to dismantle what he called iran's network of terrorism and to end ballistic missile tests. iran's presidential election was largely seen as a referendum on its nuclear deal with the u.s. and other world powers. s.izabeth palmer is in the anpital, tehran. >> reporter: a massive voter turnout clinched the election for the incumbent president and moderate, hassan rouhani. in his victory speech on state

television, he said iran had chosen a path of engagement with the world. rouhani had been running against ehe hard-liner, ebrahim raisi, whose populist campaign included cash handouts for the poor. but it was rouhani who captured ohe huge youth vote with promises to push forward liberal reforms and international relations. at lunchtime in the heart of iran's main bazaar, hungry iranians flocked to the muslim restaurant. the portions are large, and the prices low, which really matters to people because years of punishing sanctions have hurt. in fact, data from iran's central bank shows that after sanctions kicked in, in 2006, the amount of meat and rice lyanians ate at home went steadily down every year for a tcade. when the nuclear deal was finally signed two years ago, nasrin saeyfi, the restaurant's

accountant, was relieved, as everyone was, when some ifnctions were lifted, but washington's stayed in place. to have sanctions lifted ldmpletely, you would need better relationship with the united states. >> yeah. >> reporter: do you hope for this? >> yeah. sure. >> reporter: yes? >> everyone in iran hopes this. >> reporter: with 30% unemployment among young people, it's clear that iran's economy needs a major boost. president rouhani is pinning his hopes on foreign businesses to bring investment and jobs to the buntry. but judging by the hostile tone of the rhetoric coming out of the trump white house recently, not many of those companies are going to be american. reena. >> ninan: elizabeth palmer anporting from tehran. a turkish man was taken into custody friday after disrupting a flight from los angeles to honolulu. as carter evans reports, the suspect had also been arrested at the airport before the flight. 5> reporter: f.b.i. agencies
