we need to help more tocalifornians get ahead.d, that's why antonio villaraigosa brought both parties together to balance the state budget with record investments in public schools... and new career training programs. as mayor of la, he brought police and residents together to get illegal guns off the streets and keep kids out of gangs, and on the right path. that's antonio villaraigosa. a governor for all of california.

good evening, and we begin here tonight with a standoff at the mexican border. it involves a group of migrants who made a 2,000-mile trek, fleeing gang violence in their home country. they want to be granted asylum. but tonight on twitter, president trump said these migrants are openly defying america's border. abc's matt gutman is right there tonight. >> reporter: the concrete beneath these scattered blankets and makeshift tents is the only tur after that mari and her eight family members can call home right now. [ speaking spanish ] >> reporter: she is part of a group of over 150 migrants who have arrived just outside the mexican border with california, traveling from some of the world's most murderous nation, hoping to seek asylum and safety in the u.s.

it's just the latest flash point in what has been weeks of mounting tension. president trump railing against the so-called caravan. >> are you watching that mess that's going on right now with the caravan coming up? >> reporter: vowing to change the laws that allow them to come in, leaving those here in tijuana in possible limbo. after a cold night on the concrete here, people are starting to wake up. they've been here for 18 hours already, waiting for their political asylum applications to be reviewed. on buses, trains, and on foot, made the 2,000-mile-long trek over the past month from southern mexico. >> some with nothing more than a small backpack and a prayer. 150 reach the tijuana san diego border on sunday.

it's an official entry point where asylum seekers can go to plead their case. adolfo flores travelled with the caravan. >> i was on the train with a bunch of families. it was full. it was really hot, and they did not want to be there. but they knew this was better than twha what they were leaving. so they were doing it. >> reporter: but as soon as they arrived, customs border officials told the group at the crossing that it was already at capacity. but late tonight, they announced they were opening the port to begin processing again. san ysidro is one of the busiest ports in the country and frequently experiences delays. earlier this weekend, they rallied in tijuana. some even climbing to the top of the border barrier. the doj now announcing that they have charged 11 people with illegal entry into the country. but for many of the migrants, their journey began a long time. mari's five years ago. she came all the way from el salvador.

the gangs tracked her down and held her hostage in her house. and that's when she knew it was time to go. so she embarked on this process to legally enter the country. the u.s. typically grants asylum to about 20,000 people a year. >> well, the concept of coming to the united states and seeking asylum is certainly not new. in many instances they are affirmatively presenting themselves to be considered for asylum, which is a very rigorous process. >> reporter: president trump has kept a watchful eye on the caravan since easter sunday nearly a month ago. thrusting the annual caravans into the public eye. >> the one good thing, watch the caravan. >> reporter: at a campaign rally on saturday, the president doubles down. >> watch how sad and terrible it is. including for those people. because they come up and the crime that they inflict on themselves, and that others

inflict on them. because nay know once they get here, they can walk right into our country. we have the greatest people on earth, and they can't do anything because the laws are corrupt. >> reporter: and just today, the president refusing to let it go, tweeting that the migrants were, quote, openly defying our border. >> asylum is a legal pathway for someone. but if we completely cut off their ability to seek it, then we are affirmatively blocking people from a legal way of remaining in the united states. >> reporter: but for so many of these migrants, leaving their countries wasn't a choice. it was the difference between life and death. so this is the bridge over the river. in 2016 we travelled to guatemala. >> this is the legal way to do it, if you have papers. >> reporter: and the bridge is the only official border crossing for miles. we're tracing the first and one of the most dangerous stretches of the migrant trail, traveled mostly by central americans trying to escape the brutal gang violence back home.

a few blocks from the bridge, we meet edwin and jose. they come from el salvador, the murder capital of the world. jose wears his reason for flight on his back and his arms. he shows us the nickel-sized scars from a shotgun blast. he says thank god the gangs didn't kill me, because they tried. that's why we're the victims in this situation. we don't have any other option. if i go home, coy die. their home, where mari also comes from, el salvador, is one of the most dangerous countries in the world. in 2016, my colleague, "nightline" co-anchor dan harris traveled there, witnessing the violent siege that so many lives are under. there they met ariselda, whose 17-year-old son had just been killed. just two months earlier, one of her other sons was also murdered by the gang.

so she applied for asylum in america. ♪ >> reporter: they are at his wake when the unthinkable happens. [ gunshots ]

>> reporter: their story echoing that of so many who are traveling with the caravan. so these men and women, even though most will eventually be sent back to their own countries, venturing into the unknown tonight, hoping for what so many americans have and take for granted, a shot at normality. >> one of my mission to be here is to raise my boys. it didn't matter we're not from mexico, from the united states. we are human beings. we are fighting for a better future. >> reporter: for "nightline," i'm matt gutman, in tijuana, mexico. next here on "nightline," we switch gears entirely and go behind the scenes with the makeup artists for kim kardashian. how he has become a star in his own right.
