President Donald Trump fired off a series of tweets Sunday morning warning Mexico about letting illegal aliens and drugs flow through Mexico to the United States. Trump singled out the caravan of illegal migrants from Central America marching through to the U.S. with the permission of the Mexican government. Trump threatened Mexico over NAFTA and DACA if nothing is done.

Trump also called on the Republican controlled Senate to end the filibuster to pass tough laws securing the border.

Trump posted three tweets on the out of control border:

“Border Patrol Agents are not allowed to properly do their job at the Border because of ridiculous liberal (Democrat) laws like Catch & Release. Getting more dangerous. “Caravans” coming. Republicans must go to Nuclear Option to pass tough laws NOW. NO MORE DACA DEAL!”

“Mexico is doing very little, if not NOTHING, at stopping people from flowing into Mexico through their Southern Border, and then into the U.S. They laugh at our dumb immigration laws. They must stop the big drug and people flows, or I will stop their cash cow, NAFTA. NEED WALL!”

“These big flows of people are all trying to take advantage of DACA. They want in on the act!”

It is not clear if anything can be done to stop the illegal migrant caravan from entering the U.S., hence Trump’s reference to catch and release. However, pressure can be brought to bear on Mexico, as Trump is doing now.

More photos from the caravan by embedded Buzzfeed reporter Adolfo Flores:

I’m traveling with a caravan of about 1,200 mostly Central American migrants traveling through Mexico. The group is being organized by Pueblos Sin Fronteras. It’s shaping up to be the largest one they’ve ever had. Here’s a clip from yesterday. pic.twitter.com/9hQt6fb3Wv — Adolfo Flores (@aflores) March 27, 2018

The caravan is organized like an army.

Everyone is part of a group of about 10 people and five groups are put together to make a sector. Each with their own leaders and name like “Fuerza Unida,” “Unión Para La Familia,” and “Los Tigeres.” — Adolfo Flores (@aflores) March 27, 2018
