The Trump administration is monitoring a second so-called migrant caravan forming in El Salvador even as it prepares for the possible arrival of several thousand Honduran migrants in a caravan currently heading for the U.S. border.

NBC News reports that the Department of Homeland Security is watching a smaller caravan currently forming in El Salvador, including 230 members of a WhatsApp group who are planning to leave for the U.S. on October 31.

{mosads}An internal Trump administration report obtained by NBC News indicates that the early members of the caravan are families with children.

President Trump has in recent days claimed that the caravans of migrants headed toward the U.S. are infiltrated by “criminals and unknown Middle Easterners.” The caravans have captured news coverage as the president has railed against them. Trump in recent rallies has also claimed the upcoming midterm election will be defined, in part, by the caravan.

A Department of Homeland Security spokesman confirmed in an email to The Hill that the Trump administration is monitoring the El Salvadoran caravan, but did not elaborate on how DHS plans to handle the new group.

The president slammed Honduran authorities on Monday for their inability or refusal to turn back the current group that reports indicate includes 7,500 members and is due to arrive at the U.S. border within a week. Trump has promised to cut off foreign aid to Honduras and other countries associated with the migrant group.

“Guatemala, Honduras and El Salvador were not able to do the job of stopping people from leaving their country and coming illegally to the U.S. We will now begin cutting off, or substantially reducing, the massive foreign aid routinely given to them,” Trump wrote on Twitter.

“Sadly, it looks like Mexico’s Police and Military are unable to stop the Caravan heading to the Southern Border of the United States,” he added. “Criminals and unknown Middle Easterners are mixed in. I have alerted Border Patrol and Military that this is a National [Emergency]. Must change laws!”
