out it can'be overstated is that none of the lawyers we have shown you broke any laws. in part, because the african minister didn't really exist. there were no hundred of witness's representative said no money changed hand. this is sort of a morality test? >> it wasn't. it was a test on the system. >> people could make the argument, all the guys did. listened to this guy in their office. didn't make a deal. need to sign up. we need to do research. >> they would be right to say that. they need to say something. those lawyers laid out in considerable detail, a myriad of different ways to bring money into america. >> reporter: none of the lawyers agreed to take on the african minister as a client.

witness includes an opinion from two legal ethicists including bill simon of columbia. it says that if attorneys mark koplic, john jankoff and gerald ross had been responding to a real request their conduct would not comply with professional responsibilities of lawyers. it said the attorneys displayed a cynical, and evasive attitude toward law. the ethicist also noted that the rules were vague and we do not expect that all lawyers will agree with this. >> simon put then aba president james silkenaught and hugh finnegan in a different cat go, even though they provided advice on how to move questionable funds into the u.s. >> what makes him different from other lawyers? >> he was quite clear he would not assist illegal conduct. he indicated at one point he would report the client if he found the client engaged in illegal conduct. also, he was fairly clear that -- he would need more information before he agreed to

>> reporter: on the other hand he clearly seems interested in this. >> he clearly seems interested and enthusiastic about it. >> reporter: anything wrong with that? >> i find it regrettable. but i am not sure as a professional responsibility, authority, could say inconsistent with duties under the rules. >> the only lawyer who fulfilled the ideals was jeffrey herman. listened to the pitch, decided it probably involved, illegal activity and ended the meeting. >> this ain't for me. my standard are higher. not interested. >> do you know anybody who would be able? >> i don't think so. and i wouldn't recommend either. >> yeah, yeah. >> because those persons would be insulted. you can see the full two-part series on our website. cbs news..com.

history, though not the way she hoped. she was declared the winner of iowa's democratic caucuses by the smallest margin ever. now she faces a tougher battle against bernie sanders on his new england home turf next week. new hampshire is also where republican donald trump will be looking for a comeback after losing to ted cruz and barely edging out marco rubio. our campaign 2016 correspondents are on the trail. and first go to major garrett with the republicans. new hampshire. so what a victory last night. >> reporter: after earning the most iowa caucus votes in gop history, ted cruz boasted he defied the odds. >> every tv pundit on virtually every station said cruz can't win, no chance cruz is going to win iowa, not going to happen. it would be trump, trump. trump. >> reporter: but it wasn't.

gave an uncommonly subdued concession speech. >> we finished second. i want to till you something, i am just honored. really honored. today the bombast was back. trump complained on twitter he had not been given any credit by the voters for self funding his campaign and the media has not covered my long shot great finish in iowa fairly. trump called cruz's victory speech, long, rambling and overly flamboyant. the race is quickly becoming a battle among, trump, cruz and marco rubio. the florida senator says he is in better possession to be the nominee than cruz. >> who is closer now? >> i think i am. we are one delegate apart. second i give us the best chance to unify the party. you can't win if the party is divided but to grow it. >> reporter: rubio's momentum comes with attacks from kasich,

strong showings in new hampshire to stay viable. >> see if he will answer your questions, stand up and take that. i don't thing he will or can. >> what do you think that its about? >> sometimes when people are under duress they react in ways they will regret later on. christie finished 10th. cruz worked hard for his victory in iowa. holding 2/3 as many events as trump, a third more than rubio. do the math, trump collected twice as many votes per iowa visit as cruz. >> worth remembering, iowa republicans haven't picked the nominee since 2000. major garrett for us tonight. thank you. now to the democrats. here is nancy cordes. >> i am so thrilled that i am coming to new hampshire after winning iowa! >> reporter: the first woman ever to win the iowa caucuses did it by .2%. >> senator sanders are you conceding the race in iowa.

delegates down. as the i understand it, there was some precincts where -- delegates were one with the flip of the coin. we want to take a, a look at that. >> at least six precincts broke a tie with a coin toss. >> hillary clinton. >> the large turnout, evenly split, caused challenges elsewhere too. >> well should a realignment. >> in the end, 84% of young voters, under the age of 30, went for sanders. but 58% of caucus goers were 50 and up. and they went overwhelmingly for clinton. the granite state is rockier territory for clinton. the latest cbs news battleground tracker shows sanders leading in new hampshire by 19 points. his democratic socialist message plays well with the state's large independent population. >> it sounds to me like you are ready for a political

>> reporter: sanders also has something of a home field advantage here. he is from neighboring vermont. clinton has the deep ties here too, scott, it is here she staged a come back eight years ago after a stinging loss in iowa. >> nancy cordes, thank you. two casualties of the iowa caucuses, republican mike huckabee who won there eight years ago. he did poorly last night and dropped out. so did democrat martin o'malley. >> clinton picked up 22 national convention delegates in iowa. sanders, 21. but that's a little misleading because clinton already has 362 superdelegates. party leaders who pledged their votes to her. that brings her now to 384 or about 16% of the 2,382 she needs. after new hampshire, the polls indicate the primaries are expected to break clinton's way. on the republican side, cruz picked up eight delegates,

they need a little over 1,200. so, far to go. john dickerson, our cbs news political director and anchor of "face the nation." john, we heard what a difference an election makes. tell me how has the race changed? what's the new framework? >> we have been talking about the race in terms of establishment, versus the outsider. woe we shoe look, ideology, versus electability. look at entrance polls in iowa, who shares your val use? they went for ted cruz. when they were asked who do you think can win in november, the large share went to marco rubio. going into new hampshire, ted cruz is saying i'm the true consistent conservative. the keeper of the flame. rally to my light. marco rubio is saying i can beat hillary clinton. >> question of yesterdayology and electability. tell me where does this go from here? >> well, marco rubio did well in

better than expectations. but now he is saying he is in the top tier, he is the alternative to cruz and trump. those expectations are very high. so, he would have to do very well in new hampshire which is a less ideological state. of course he has new competitors there in bush, christie, and kasich. all of whom want to drag him down. of course there its the roiling fight between ted cruz and donald trump. >> john dickerson. watching on sunday on "face the nation." john, thank you so much. the "cbs overnight news" will be

and they're present in much lower numbers where they are present. second, because people have air conditioning, are inside, legislation crowded than some of the places where zika is spreading so rapidly, we are much less likely to have the widespread transmission even in the places where are the mosquitoes that spread this virus. >> dr. thomas frieden of the cdc. turning overseas -- there was a bang and suddenly a gaping hole in a jetliner over war torn somalia today. margaret brennan has the that. >> reporter: cell phone video shot on the plane while still in flight shows oxygen masks fwloeg in the wind near the hole in the airbus 321. some passenger toward the back of the plane can be seen wearing oxygen masks. on the ground the damage to the plane was clearly visible with pieces of the fuselage curled out from the body of the plane. all 74 passengers and crew were evacuated.
