Since peaking at around 1,500 people, the caravan has dwindled after Mexican authoritIes issued permits shielding many from imminent deportation from Mexico.
The Mexican government has denied that it is allowing the migrants to travel unimpeded across its territory.
Organizers had originally made bold claims that they would take the 1,500-strong group of invaders to the U.S.to either demand asylum or outright evade USA law enforcement.
After fleeing San Pedro Sula, Honduras, because of gang threats, Katerina Dominguez Enamorado, 22, had been in Tapachula, a southern Mexico town, when she joined the caravan.
Last year, about 150 people made it all the way to the USA border.
Once again, President Trump has talked about rapists in Mexico, and left consternation and confusion in his wake.
Organized by a group of volunteers called Pueblos Sin Fronteras, or People Without Borders, the caravan is meant to help migrants safely reach the United States, bypassing not only authorities who would seek to deport them, but gangs and cartels who are known to assault vulnerable migrants.
A boy sits awake as Central American migrants traveling with the annual "Stations of the Cross" caravan, sleep at a sports club in Matias Romero, Oaxaca State, Mexico, Tuesday, April 3, 2018. The immigrants who take part in the tradition, some say, only do so because they seek protection from some of the most unsafe countries in the world.
Pena Nieto added, addressing Trump, "if your recent statements are derived from your frustration with (U.S.) domestic politics, with your laws or your congress, deal with them, not with us Mexicans".
One of the most striking electoral promises of the Donald Trump campaign was the construction of a wall on the border with Mexico to block illegal immigration.
Jorge de Santiago, a maquiladora worker whose house sits right on the border, said of the deployment: "It looks bad, but it doesn't do much". Rodrigo Abeja, one of the organizers, said help was being sought from a breakaway faction of Mexico's teachers union, which has years of experience convening large protests and is generally aligned with the country's leftist presidential candidate, Andrés Manuel López Obrador. Mujica said that "a minimum of 80 percent" of the migrants in the group come from Honduras. "And now they're beating us economically, they are not our friend believe me", he said at the time. Trump's comments have turned the event into a fresh source of tension between the United States and its southern neighbors.
"You take the risk of staying in your own country, where they are going to kill you, or you take the risk of taking this path, which is unsafe", Bonilla said. The cultural diversity is a reminder of why people moved here in the first place. "We will act only in the best interest of Mexican". These are the types of investments - not a further militarized border - that will lead to more sustainable solutions for the United States, migrants, and their home countries.
