president trump getting straight to work on his first monday on the job signing orders overturning some of president obama's economic agenda and meeting with top business leaders. this after a tumultuous weekend of protests and a contentious press conference. trump beginning his presidency in true trump action with decisive action in the face of controversy. here's my "nightline" coanchor juju chang. >> it's going to be only america first. >> we will not go away! >> dangerous and destructive on day one for the press to be reporting false information like that. >> reporter: from the pulpits of power to the marching of millions. >> it took this horrific moment of darkness to wake us the [ bleep ] up. >> reporter: the first three days of a new american era, classically trump. unconventional and contentious. his first days in office, his top advisers being sworn in. >> i, state your full name --

>> reporter: from kellyanne conway to son-in-law jared kushner. a new cia chief confirmed. on his first monday in office, a meeting in the oval with top ceos from ford, to whirlpool. three presidential memorandums signed on trade, a federal hiring freeze, and cutting funds to global agencies that promote or pay for abortions. >> before i get to a policy question, just a question about the nature of your job. >> reporter: it was the briefing with press secretary sean spicer that everyone was waiting for after that controversial one over the weekend. >> this was the largest audience to ever witness an inauguration, period! >> reporter: the proof is in the pictures. >> we know that 420,000 people used the d.c. metro public transit yesterday, which actually compares to 317,000 that used it for president obama's last inaugural. >> reporter: in fact, he got it wrong. repeatedly. ridership, for example, was not bigger for trump's inauguration. but that didn't stop kellyanne conway from doubling down on

sunday morning's "meet the press." >> you're saying it's a falsehood, and they're giving, sean spicer, our press secretary, gave alternative facts to that. >> look, alternative facts are not facts. they're falsehoods. >> reporter: the internet had a field day. alternative facts and spicer facts trending. merriam-webster tweeting the definition of "fact." george w. bush's press secretary ari fleischer says spicer shouldn't have delivered provable falsehoods. >> his briefing made me uncomfortable. too truculent, too tough. it looks as if the ball was dropped on saturday. >> reporter: abc's jon karl going head to head with spicer. >> is it your intention to always tell the truth from that podium, and will you pledge never to knowingly say something that is not factual? >> it is. >> do you have any corrections that you would like to make or clarifications from saturday? >> ask away. >> reporter: the new press secretary walking back some of his claims. >> we were trying to provide numbers that we had been provided. that wasn't like we made them up

out of thin air. >> reporter: holding firm on others. >> 31 million people watched on television. combine that with the tens of millions of people that watched it online, on a device. it's unquestionable. >> reporter: and pointing the finger at a "time" magazine reporter who tweeted erroneously that a bust of martin luther king jr. was removed from the oval office. >> think about how racially charged that is. and someone rushes out and says to the entire press corps that the president of the united states has removed the bust from his office. >> spicer had basically a reset to do after what happened over the weekend, coming into this briefing room, lecturing the press, getting a couple of his facts wrong, not taking any questions. very combative. this was much less combative. there was certainly some combat going on. but definitely a reset in terms of his relationship with the press. >> reporter: what is unquestionable, the unexpected size and scope of the women's march on saturday. dwarfing the inauguration's

crowds in washington and more than 60 cities around the world. for most of these people the day started at dawn, getting on a bus. it's now 4:00 in the afternoon. six hours into the protests. and the enthusiasm is still high. >> we are here to be respected. >> reporter: on the mall, famous faces standing in solidarity. >> in the face of this current political climate, it is vital that we all make it our mission to get really, really personal. >> reporter: the demonstration, for many, it's their first time. a medley of issues. workers' rights. abortion rights. gay rights. immigrant rights. >> basically i am here in support of my mother, my girlfriend, every woman that i know and love who i feel has been insulted and misrepresented and denigrated by the new president. >> reporter: chris danner traveled here from new york. that's the one criticism that a lot of -- that you hear a lot that you're being sore losers, you should get behind the

president. >> oh, well -- on one hand, we are the majority of americans. i mean, he lost the popular vote by 3 million votes. there is no one claiming that he is not our president. but to say -- to voice your opinion is incredibly patriotic and american. >> reporter: voices united. collectively trying to get the attention of the new president. ashley judd's speech going viral. >> i am a nasty woman. >> not as nasty as a man who looks like he bathes in cheeto dust -- >> reporter: the poet behind those words, 19-year-old nina donvan. >> i just thought it was important to remind women, especially people as young as me, there is so much hope and there is still so much respect left in the world. >> hell yeah! >> that's what we need to continue to fight for. not attack each other, but fight

with our words, fight with our peaceful protests. >> millions of people not only in this country but all over the world telling mr. trump that his agenda is not the agenda we need for the year 2017 and the future. that women will not be second-class citizens. that we cannot think that climate change is a hoax. i would hope that mr. trump got the message. that an extremist agenda is not what the people of this country or the world want to see. >> reporter: the marchers disrupting the president's first full day in office. the protest organizers say it was too big to march past the white house, but it's just there, you can see it. you have to wonder if he can hear the chanting of the crowd. trump was on his way to the cia where he lashed out at the media in front of the memorial wall. >> we caught them in a beauty and i think they're going to pay a big price. >> reporter: not everyone was

welcome at the party. >> there's a lot of women who think we don't belong here because our signs say "abortion betrays women." but our message is a pro-woman message. >> reporter: kristen hawkens says planned parenthood sponsorship left anti-abortion groups like hers on the sidelines. >> feminism could be the discussion of how is it we can make sure we doesn't have to choose between killing her child and fulfilling her dreams? that's the discussion we should have. that's something that i think there's common ground on. >> reporter: trump's new d.c. hotel became a de facto target of the marchers. >> shame, shame, shame! >> reporter: so did his supporters. out on the sidewalk, it was pink hat versus red hat. >> i support you. i do, i support you. >> move along, move along. >> i support you. >> move along. >> quit the divide. >> love is supposed to trump hate. this is hate. >> reporter: rebecca says she campaigned for trump and came to d.c. to celebrate his inauguration.

>> i went all around the east coast knocking on door to door, and this is my reward. now they've ruined it. >> reporter: early sunday morning, a series of tweets from trump seemed to indicate the women's march had gotten under his skin. "watched protests yesterday but was under the impression that we just had an election. why didn't these people vote? celebs hurt causes badly." later a change of tone. "peaceful protests ar hallmark of our democracy. even if i don't always agree, i recognize the rights of people to express their views." >> to the extent that president trump saw this as yet another in his view attempt to delegitimatize his presidency, he didn't like it. but it was so joyful and so successful that by the end of the weekend, he was tweeting about the importance of dissent. >> we will not go away! >> reporter: those voices of

dissent, a call to arms for the resistance. next, women marching in solidarity across the country. undocumented immigrants asking for their shot at the american dream. their messages to president trump.

over the weekend, millions of americans across the country marched against president trump's agenda. tonight we'll meet some of the vulnerable people depending on those demonstrators to be their voice, the so-called dreamers. young undocumented immigrants who fear their lives will be upended if the president follows through with some of his campaign promises. here again is my "nightline"

coanchor juju chang. >> we just met up with this group from new jersey. they are the daca kids whose futures are literally hanging in the balance of the next trump executive order. >> reporter: hanging in the balance because under a trump administration, this sliver of young professionals runs the risk of losing their temporary deportation relief. granted under president obama. under an executive order called daca, deferred action for childhood arrivals. >> it's symbolic for me fighting back to what i think is unjust. >> reporter: in the crowd stood sarah mora. >> i'm a daca holder, an immigration policy that right now is helping a lot of college students. >> what are the dangers of having it removed? for you?

>> my life would crumble. because everything that we have through daca is holding us together. license, work authorization. it would mean for a lot of people going back to their country or fighting back and that's what we're doing right now. >> reporter: a college student who says she too came to the u.s. when she was just 4 years old. >> how did you come to this country? >> we came with a visa. airport, a plane. >> tourist visa? >> yeah. >> your whole family's undocumented? >> right. >> reporter: originally from costa rica, her father works as a truck driver. her mother cleans houses for a living. mora, the oldest of three, hopes to one day be a diplomat. >> it's putting our lives into perspective. it's like, all right. we're in this limbo, not sure what's going to happen in the next months. >> it's an existential crisis for you. >> right. >> reporter: a crisis after a campaign season where undocumented immigrants were often the target of trump's scorn. >> they're bringing drugs, they're bringing crime, they're rapists. we have some bad hombres here. we're going to get them out.

we're building the wall, believe me. believe me, we're building the wall. >> reporter: at one point telling "meet the press" -- >> they have to go. >> what if they have nowhere to go? >> we'll work with them, they have to go. >> reporter: today press secretary sean spicer addressing the looming issue. >> tures and foremost, the president's been very, very clear, that we need to direct agencies to focus on those who are in this country illegally and have a record, a criminal record, or pose a threat to the american people. >> i'm not afraid of trump or anything that he can do, i'm afraid of the people not standing up to stop him. >> reporter: lee adorno, a college senior, says losing his daca rights means he'd lose the only legal way he's able to make his family make ends meet. >> without that it puts me in a situation where i have to go back to working under the table, doing something illegal. >> reporter: similar to that of his father, one of 11.4 million undocumented workers currently in the country. >> he doesn't get benefits. he has to work less than minimum wage. and he can't take days off because if he does, they'll fire

him. that is inhumane. that goes against everything that the country stands for. >> reporter: lee telling us he's sharing his story not for pity but because he's seeking justice, dignity, and respect. >> what do you dream about? the future? >> boy, i don't even know. i don't want to let myself get into that zone. because i feel like, for what? you know? there's a real, real chance that none of them might happen. >> reporter: yet throughout the day, signs of solidarity. >> the greatest part of america is right here this group. we're all immigrants. and we are the most recent immigrants. you need to stay here and make our country as great as it is. >> there's a real convergence of people kind of colliding in groups with different agendas. all sort of high-fiving each other along the way. and all coming together. hello. the veritable buffet of issues being championed confuse some. >> i don't think half these people really know why they're

here. like all these people walking by, climate change. okay, cool. we can come together. >> i think the variety of causes make it hard to get organized around a single issue. it wasn't a march to pass the civil rights bill of 1964. or to end the vietnam war. my greatest hope out of this march is that more women will run for office. >> reporter: many marchers say they saw their diversity as a plus. >> have you panned the group here? we're not all the same, we're different, how wonderful. we're the melting pot that america was supposed to be. >> i'm down here just to march for future generations. to fight for all rights, including lgbt, muslim rights. >> so marching today in the parade, what was that like for you? >> it was awesome. it's my first time i've ever marched.

it was important to me and it was important to get my children out here, to let them know that you have to stand up for what you believe in. >> the big challenge is keeping the momentum moving forward. but right now, people are so excited, they loved being together. >> reporter: one of the organizers of the women's march, linda sasour, says that's her goal. >> i think people are finally awake. a lot of communities of color, we've been experiencing marginalization at the hands of government for a long time, and suddenly our white counterparts woke up and i'm glad they're here. >> i stand here before you unapologetically muslim-american. >> reporter: she says she's already personally feeling the new wave of support after being targeted on social media for being a muslim. thousands leapt to her defense. >> i don't know, some great amazing people created a hash tag called i march with linda to counter the vitriol out there. >> reporter: to critics who say the march was a one-shot deal, she says wrong. >> the women's march on washington has created an infrastructure, whether we like it or not.

we have over 400 organizers around the united states of america. we're not going to drop that because we had one great march. we already made history. >> reporter: for "nightline," i'm juju chang in washington, d.c. >> our thanks to juju and our team for that report. we'll be right back. more people than ever are choosing nissan... making us north america's fastest growing auto brand in 2016. take on 2017 and get the safety you'd expect... the fuel efficiency you need and america's best truck warranty. get to nissan's take on 2017 event for 0% financing for up to 72 months on 11 models. or save up to $10,000 on select models. ♪ of being there for my son's winning shot. that was it for me.
