>> hollywood called and she became a supporting actress in a number of films including the "the next voice you hear" with james whitmore. davis was introduced to the head of the screen actors guild, his name was ronald reagan. she would later say, "being his wife was the role i wanted most." >> i was afraid you wouldn't come." "hellcats of the navy" the only movie they made together. but as his trajectory took him away from hollywood she was in the front seat with him. many said she was more ambitious than she was. when they won the white house, the country was amazed by the gaze, the adoring look of a woman who said her main job in life was protecting him. but sometimes she couldn't. >> the president -- >> there was the assassination attempt in 1981. >> how yur -- how are you sneelg sneelg. >> and his bouts with cancer. nancy reagan had her critics.

$200,000 white house china during a recession. the president defended her. >> there has been no new china for the white house since the truman administration. >> there was perhaps no greater example of how close the reagans were, than when the president was asked a question, and the first lady fed him an answer. >> we're doing everything we can. >> thank you, sir. >> hello. to all of you listening out there. >> nancy reagan used her influence as first lady to set up a campaign to try to keep kids from taking drugs. >> i can't hear you? louder! that's wonderful. >> five years after the reagans left the white house the former president announced he was battling alzheimers disease. mrs. reagan spoke about it in an interview with mike wallace on "60 minutes" in 2002. >> that's the worst part about this disease, there is february to exchange memories with.

from public view, his best supporting actress moved to center stage. >> she went to his birthday party alone. >> i would like to propose a toast to my fella. >> reporter: she signed his books for him. christened ships named for him. and received medals awarded to him. there were tributes today from across the political spectrum. her strength of character was legendary said president clinton and secretary clinton. she leaves a remarkable legacy of good. her influence on the white house was complete and lasting. wrote president and mrs. george w. bush. from president jimmy carter. theirs was one of our nation's great love stories. and a model of shared devotion to our country. sending condolences on behalf of herself and president george h.w. bush, barbara bush said, we take comfort that they will be reunited once more.

[ applause ] >> reporter: she really was the power behind the throne. nancy reagan spent her life protecting her husband. she did all the worrying so she didn't have to. and it was her instinct about people which in most cases decided who would work for ronald reagan or whose usefulness had expired. jeff. >> one thing watching the white house, and covering it. you also had several memorable encounters with nancy reagan, did you not? >> yeah, several. the big one at a reception when i introduced my date to her as my all most fiancee.

and she said, get her a ring. i did. >> bill plante in our washington bureau. bill, thank you very much tonight. >> the republican presidential candidates paused to pay tribute to nancy reagan. here's julianna goldman. marco rubio called nancy reagan a true example of integrity and grace. in another tweet, ted cruz said she will be remembered for her deep passion for this nation and love for her husband. an amazing woman wrote donald trump. news of nancy reagan's death came on a day when most candidates vying to inherit ronald reagan's conservative legacy were taking a break before the next round of critical contests. >> she is now, as she used to say, "with her ronnie." >> john kasich was the exception. campaigning in his home state of ohio, alongside arnold schwarzenegger. looking beyond the four states he lost yesterday. >> marco ruby had a very, very bad night.

louisiana saturday. but lost to cruz in kansas and maine. rubio like kasich was 0-4. last night trump called on the florida senator to drop out. >> i would love to take on ted one-on-one. that would be so much fun. >> cruz seemed to agree. >> if you are not able to win primaries, not amassing enough delegates to get the nominee, every candidate has to reflect. >> while rubio insists he will win his home state of florida. some unlikely republicans are coming around to cruz. like lindsay graham said this to say. if you killed ted cruz on the floor of the senate, and the trial was in the senate. nobody could convict you. today he said the gop need to up night before march 15. >> to me it is clear that ted made the best case thus far that he can be the alternative to trump. rubio is rejecting call to drop out before march 15th.

his second win. the associated press has said ruby has won the puerto rico primary that means he will likely take the territory's 23 delegates. >> thank you. the "cbs overnight news"

>> i am thrilled we are adding to our pledged delegate count. >> reporter: here in michigan, landslide victory in louisiana. bernie sanders won in kansas and nebraska. but the states are smaller and so clinton ended up with 55 new delegates. sanders, 47. sanders still insists he's the one gaining steam. >> honestly i belief i am the candidate to create that large voter turnout and make sure that we retain the white house. >> reporter: to prove that he will have to catch up to clinton in michigan. she spent the weekend visiting african-american churches in detroit. >> madam president. >> not yet. >> that sounds good. >> sanders took another approach.

secretary clinton's. >> reporter: hammering clinton for past support of free trade deals in a state hit hard by foreign competition. >> in every major trade agreement i have not only voted against them but helped lead the opposition. made flint's water crisis a personal cause. >> clean water is not optional, my friends. >> clinton brings it of in almost every speech. we have to support them until the all city's families have clean, safe water. on face the nation, john dickerson asked clinton while republican turnout is up. and democrat turnout is down. >> i have gotten more votes. than any body running on either side. i have gotten more votes than donald trump. sure he doesn't want to hear that. >> michigan with 130 delegates one of the largest states the candidates have competed in so far. not only reason it is important. they see the state as bellwether for other rust belt states. ohio, indiana, illinois. that's what makes to night's debate more high stakes than usual. jeff, especially for sanders.

what that means. you know, i have gotten more votes than anybody running. on either side. i have gotten more votes than donald trump, although i am sure he doesn't want to hear that. and we have gotten it from a wide, broad base. i have gotten in the democratic primary, election, i have gotten more white voters except for the state of vermont all told. all told i have had more support from white voters. i feel really good about where our campaign is and where it is going. >> in places like ohio, massachusetts, there are reports that democrats, switching over changing their registration, becoming republican sews they can vote for donald trump. aren't those voters you are going to want back. how do you get them back? >> well, i want to get every voter back. i will keep working during the primary to earn every vote. and make it clear i am running an inclusive campaign the i want

americans not just some of them. and i hope that, as we move forward, people will be giving a second, third look to all of the candidates. and that includes me. it include, mr. trump. so i am going to keep reaching out. and demonstrating unequivocally if people are frustrated, discouraged, upset by what is happening in the economy or the government or political system, that i come ready, prepared, to progress. i think that is a very strong case. >> let me ask you a question about something in the news this week, brian pagliano, former state department staffer, who was granted immunity from prosecution into the criminal server. when this happens. worry somebody is going to get >> well there is no basis for that. i am delighted that he has agreed to cooperate as everyone

marco rubio won the gop primary in puerto rico. but remains far behind in the delicate count. -- behind in the delegate count. ted cruz says he is the only republican that can block donald trump from winning the presidential nomination. saturday, cruz won in kansas and maine. trump won louisiana and kentucky. both trump and cruz spoke to john dickerson for "face the nation." >> conservatives talked about the coarsening of the culture and job of a conservative politician to stand up and say "no more."

culture? or made it worse? >> well, listen, there is no doubt there are aspects of the campaign that have gone into the gutter. we saw moments with donald trump and marco rubio engage in insults. offcolor jokes, nastier and throwing mud. my approach, i am not going to play, not going to engage in the insults and throw the mud. i don't have the views on the size of any parts of donald trump's anatomy. i am not interested in talking about that. what i am interested in talking about is issues facing american people. millions are facing stagnant wages not having jobs. my top priority is bringing back jobs and raising wages. we will do that by revealing obama care, passing a flat tax. abolishing the irs, stopping amnesty, securing the border that's my priority. >> you said last week talked, donald trump is entertaining. it's entertaining. other stuff slips in that's the way in which conservatives i talk to for years have said that's the way the culture slips.

stand up and say no there are guardrails here. >> listen, think about what presidents have meant in history. lincoln's gettysburg address. fdr, only thing we have to fear is fear itself. jfk, ask not what your country can do for you, ask what you can do for your country. i think people at home are asking themselves, how would we feel if our children came in repeating the word of the president of the united states. if that president was donald trump. if it would embarrass you to have your children repeat the word of the president, that's not a good thing. a president should unifiep, appeal to our better angels, appeal to our shared val use that make america who we are. and that is how i am trying to campaign. i think that's what the american people are looking for. >> donald trump said there need to be flexibility on m immigration. you talked "the new york times." and off the record conversation. he is right of course. negotiation. flexibility. right? >> he is most absolutely not right. but it was a stunning aspect of the debate. he said over and over.

flexibility. flexibility. that's one of the reasons why we are selling now, yoga mats on our website. tedcruz.org. they're breathe yoga mats. if you find yourself, boiling over with rage. spend time doing yoga. breathing maybe help you relax. listen, conservatives are used to seeing republican candidates run to the right in the primary. run to the left in the general. part of the reason we are frustrated. angry. we are tired of politicians lying to us. what was amazing about the debate, john, donald is running to the left. he is not out of the primary. in the debate this week. donald stood up there and said to marco rubio, i agreen with you, i understand why you compromised and were flexible negotiating with chuck schumer on the gang of eight. this is the donald trump who has made immigration the centerpiece of his campaign. who said he agreed with marco rubio supporting the gang of eight amnesty bill. stunning. >> last question, something that

you talk about he is going to be a president. you can't let your children watch tv. marco rubio says he is a con man. all these terrible things. at the end you are asked if you will support him. you do. doesn't that undermine the criticisms say he will be a danger to conservatism and republican values. >> listen, one, hillary clinton as president would be more catastrophic. a third term of barack obama. i cannot support hillary clinton. number two at the outset of the campaign. i promised i would support the republican nominee. i am some one who keeps his word. past week on super tuesday. in the state of texas. we won an overwhelming victory by 17 points. that was particularly meaningful. the people of texas, they know me. and they know my heart. they are people i made promises to. i ran for senate. you elect me. i will lead the fight against obama care. amnesty, lead the fight against our debt. and lead the fight to protect

the reason we won in texas, texas said, ted you kept your word. i will tell you, john. as president i will do the very same thing. >> mr. trump you are bringing a lot of new people into the republican party. some people are saying they want to leave the republican party too. what is your message to those who want to leave? good riddance? >> i think they shouldn't leave. i think they should get together. i think everybody should be unified. we are building up numbers incredible within the republican party. you have been seeing, south carolina, new hampshire, the numbers are astronomical. i don't think they have ever seen anything like this, actually. by the way the democrats are losing. democrats are going down, 35%, 40%. we are going up 50%. couple states over 100%. >> what do you make of the effort to try to take the nomination away from you by going to the convention?

party the i will appoint conservative judges. and a third party would mean that him ear would win or who ever is going to be running. you are going to have liberal judges as many as four or even five if you can belief that during this, period of time. so a third party means absolutely they will have four or five very liberal judges appointed as owe posed to four or five, very conservative judges. i think it is really playing with fire. >> they say they can't be in the party with you as head of it? >> i've don't understand that. i get along with people. very much a unifier. maybe people don't see that. they will see that. my relationship to people has been great over the years. i am new to politics. months. job in seven months. of people coming in and showing the lines in all the states that i have won have been record setting. >> in this very room, a big night or superer tuesday, you

if you didn't. he will have to pay a big price. you said about john mccain. he has to be very careful. how can you be a unifier when you are saying those things about two republicans. >> i think he would pay a big price. you'd really have a split party. a very split party. he has done a good job. i may be mr. conservative than him. i am stronger on the border. but he has done a very good job. i was in favor of paul ryan. he very much is a unifier. he was sort of chosen i think. >> a lot read that as a threat. >> not ape threat. not a threat. >> paul ryan said, if a person wants to be the nominee of the republican party. no evasion and no games. they must reject any group or cause built on bigotry. he was talking about you. >> i have rejected. how many times do i have to reject. i reject david duke. rejected david duke. i have rejected the kkk, the ku

years old. i rejected them. president of it on twitter last week. how many times. an amaze thing with twitter. i have, more than 6 million. and another 6 million with facebook. 13 million, 14 million with instagram. when i put out a minor message. everybody picks it up. donald trump tweeted something very unimportant. let me just explain -- when i put out that i reject the kkk, david duke. nobody picks it up. you know why they don't? they don't want to pick it up. you pick it up. everyone picks it up. simultaneously. practically the same time. they don't want to pick it up. i have been asked this question so many times. i have rejected. so many times. what did you think about ryan saying that? i guess that was my question. >> don't forget. he is getting a lot of information to you guys. when i tweet about a rejection almost right after the show ended. maybe i wasn't clear or something. how many times do i have to sach if it? i told cnn when chris christie endorsed me.

question was asked. i rejected it there. news conference was a day before. how many times do i have to reject or disavow. >> let me ask you this question. david duke is saying to his supporters and followers, vote for donald trump. white supremacists are saying. do you want the votes? >> i don't want them. i don't want him to. i can't help it. if he says it. but i don't want it. john, if he says it, he says it. do i want it, no. no, i don't want anything. >> white supremacists. >> i don't like any group of hate. hate groups are not for me. but i have said this before -- the press hates me to say it. they just don't want to pick it up. >> you are turning, thinking more about the general election. in december last year, you said, talking hillary clinton. we view this as the war. then you asked the audience, don't we view this as war? do you still view it as war? >> little bit. yeah, look it is highly competitive.

against is me. i can tell you that. i know that. sort of interesting. one of your competitors said, i know that hillary clinton wants to run against donald trump. i called him. i said, listen here's the story. if they say they want to run against me that means, they don't want to run against me. do you understand that. because that's the way, a game of chess. i know for a fact. and you know for a fact the last person that she wants to run against me. i've won numerous polls against hillary. i haven't started with hillary. i had a brief moment weeks go. hillary went way down and bernie got credit. running a great campaign. >> the "cbs overnight news" will be right back. i think we should've taken a left at the river. tarzan know where tarzan go! tarzan does not know where tarzan go. hey, excuse me, do you know where the waterfall is? waterfall? no, me tarzan, king of jungle. why don't you want to just ask somebody? if you're a couple,

it's what you do. if you want to save fifteen percent or more on car insurance, you switch to geico. oh ohhhhh it's what you do. ohhhhhh! do you have to do thattright in my ear? choose to move freely. move free ultra has triple-action support for your joints, cartilage and bones in one tiny pill. move free ultra. get your move on. and now try move free night. the first and only 2-in-1 joint and sleep supplement. because i'm a woman... do you think i'm gonna crack under pressure or conquer the field? defy expectations any day with always infinity. made with flexfoam. absorbs 10x its weight. rewrite the rules. always. this is mineral build up it collects leaving gross germ-ridden stains. clorox toilet bowl cleaner with bleach is no match for that. but lysol power toilet bowl cleaner eliminates mineral build-up effortlessly. so why choose anything other than lysol? jill and kate use the same dishwasher. same detergent. but only jill ends up with wet, spotty glasses. kate adds finish jet-dry with five power actions
