After being temporarily halted by Mexican police in riot gear as they tried to cross the Guatemalan border in Mexico, the group reorganized and vowed to march to the United States border. "Criminals and unknown Middle Easterners are mixed in", he said on Twitter.
President Trump has declared that the US will start blocking federal aid to Central American countries for failing to to contain the migrant caravan. Watch Pete Hegseth bring that up in the video above, and make the leap to tie that comment to the caravan of immigrants.
Trump offered no evidence that anyone from the Middle East is with the Central American migrants.
Later in the day, authorities in Guatemala said another group of about 1,000 migrants had entered that country from Honduras.
The caravan of migrants mostly from Guatemala and Honduras bedded down Sunday night on the concrete of a town square in Mexico but awoke Monday determined to resume their arduous journey to the USA border still some 1,700 miles away. Honduras received $175 million, and El Salvador received $115 million.
Last week, Trump said he could mobilize the USA military and shut down the border if the migrant group didn't turn around.
"Full efforts are being made to stop the onslaught of illegal aliens from crossing our [southern] border", he tweeted.
"People have to apply for asylum in Mexico first, and if they fail to do that, the United States will turn them away".
Early this morning, United States President, Donald Trump dropped a bombshell announcement on Guatemala, Honduras and El Salvador.
"We are going to sleep here in the street, because we have nothing else", said Jose Mejia, 42, a father of four from the Honduran city of San Pedro Sula.
President Trump has been incensed over the group of around 5,000 migrants, mainly Hondurans, who say they are fleeing violence, poverty, and corruption in their homeland.
Mexico's government has said throughout the past week that it would register the migrants and process requests for asylum.
Trump has raised alarm over a group of thousands of migrants traveling through Mexico to the USA, saying, "Sadly, it looks like Mexico's Police and Military are unable to stop the Caravan".
They aren't the first Central American migrants to chart that path.
"While we closely monitor the caravan crisis, we must remain mindful of the transnational criminal organizations and other criminals that prey on the vulnerabilities of those undertaking the irregular migration journey", Ms. Nielsen said in a statement Sunday.
