After his tweeted threats to cut foreign aid payments to Honduras, Guatemala, and El Salvador apparently failed to affect the massive caravan marching toward the U.S., President Trump ramped up the rhetoric and included a new target: Mexico.
At a rally in Missoula, Montana, President Trump accused Democrats - without any evidence - of supporting a caravan of about 3,000 Central American migrants heading for the US border and said the upcoming midterm vote will be "an election of the caravan".
In a series of tweets, Trump said that if Mexico is incapable of stopping the immigrants, he will "call up the U.S. Military and CLOSE OUR SOUTHERN BORDER!"
The Mexican visit is important for future relations because it comes just ahead of the inauguration in December of President-elect Andres Manuel Lopez Obrador. "There's no reason to give them greater transcendence or importance", Videgaray said from the United Nations where he sought the world body's help processing asylum requests from the migrants.
Migrants regularly float across the Suchiate river on rafts, then wind their way north through Mexico, sometimes choosing to travel in large groups for protection.
The migrants are fleeing Honduras where they say they have no prospects.
Late on Thursday night, a small number of the Honduran group who broke off from the main crowd were able to successfully cross over into Mexico.
"Anyone who wants to work in our country ... will have a work visa", he said.
"Mexico's policy consists in respecting and protecting human rights" of migrants, Mexican Interior Minister Alfonso Navarrete said earlier this week.
The group chanted: 'We are not smugglers, we are migrants, ' as they reorganized themselves on Friday afternoon.
By Thursday the convoy, which set out from the violent Honduras city of San Pedro Sula on Saturday and is now believed to be around 3,000 people strong, was moving up towards the Guatemala-Mexico border city of Tapachula.
Mexico's ambassador to Guatemala says his country has made a decision to enforce a policy of "metered entry" since thousands of migrants are clamoring to cross.
"In other words before they make the trek across Mexico?"
They may not be behind the wheel, but Democrats have driven illegal immigrants in the migrant caravan to the USA border, President Trump asserted during a raucous rally in Montana Thursday night.
"Well, we're looking at a lot of things", he said.
The exhausted migrants - mostly from Honduras and Guatemala - slept under rainy skies on the streets and in a park in the border town of Tecún Umán, where the shelter for migrants and a local Catholic parish were filled to capacity.
USA secretary of state Mike Pompeo is preparing to set off on a tour of the region.
He posited that the Trump administration could coordinate with Mexico and Central American countries regarding the potential deployment of USA forces to aid as far as Mexico's border with Guatemala.
