But the simple truth is that of this so-called caravan, the vast majority of migrants are on foot and still more than 1,000 miles away from any US border checkpoint - meaning that it will be a month, if not longer, before any crisis would even occur.
The Pentagon is expected to deploy about 800 troops to the US-Mexico border, two US officials told AFP on Thursday, after President Donald Trump said the military would help tackle a "national emergency" and called on a caravan of US-bound migrants to turn around.
"They don't want you to see this".
The migrant caravan as of Thursday is still in southern Mexico, more than 1,000 miles away from the nearest entry point into the U.S. Its size is estimated to be around 7,000, but many of those now walking are suffering from exhaustion, dehydration and heat stroke.
Some of them, including women and children, have said they're fleeing because of widespread violence and poverty.
The other image of people outside coach buses is credited to Jose Castanares and taken for AFP/Getty Images in April of this year, when another migrant caravan was enroute to the United States. Trump wrote on Twitter, referring to the migrants.

Mexico vowed not to bow to outside pressure to halt the caravan.
According to the mexican government, 1.743 people who are part of the caravan have already filed an asylum application in the past few days. "If the United States would investigate more about what happens in our country, they would be convinced that what we Hondurans say is true". Nielsen responded that Bolton, not a frequent attendant of the immigration meetings, was no expert on the topic, they said.
The caravan consists of an estimated 7,000, though estimates range from 3,500 to 10,000. Migrants are also taking it upon themselves to pick up after themselves.
Another group of about a thousand Honduran migrants is making its way through Guatemala on foot towards the Mexican border, Guatemalan police confirmed Monday.
The caravan of Central Americans trekking to the United States shrank when 500 accepted bus trips back to their home countries and hundreds of others dropped out or were granted asylum in Mexico, authorities said.
Caravan members also face the threat of being robbed, kidnapped or killed by Mexican gangs that extort migrants on their journey. Last September, 32% were family members and unaccompanied children.
"He wanted to go back to Honduras. But I explained we can't go back, that the situation in our country is too hard and that's why we had to run away", she said quietly.
