RIO GRANDE VALLEY, Tex. (KWTX, WMTV)--- Border Patrol agents trek through a rain-soaked field in the dead of night. They are tracking one of dozens of groups of migrants who will cross illegally in-the-course of a day here.
So far, two apprehensions. They are Mexican males, 23-years-old. This plays out every day, every hour," says Deputy Chief Raul Ortiz of the Rio Grande Valley Sector.
It is a scene exclusively witnessed by KWTX Anchor Tara Mergener. KWTX is WMTV's sister-station in Waco, Texas.
Ortiz believes the others in the group who ran from agents, have likely made it to a nearby stash house. If they are not caught, most will find their way to larger cities and slip into society, he says.
While agents search and handcuff two men, surveillance quickly spots more rafts full of migrants on the river trying to make landfall. A smuggler is seen keeping watch from the Mexico side.
The smuggler's goal is for migrants to put their feet on U.S. soil, before agents can turn them around.
"We probably have just in this one station a hundred people crossing right now. They are mostly coming from Guatemala, Honduras and El Salvador, says Ortiz, A wall would have slowed them down considerably."
On the journey, some are hurt, many report they are raped, most have traveled for weeks through many countries to get here.
Like the tens of thousands of others who will sneak around legal ports of entry this month, Oscar turns himself in and plans to seek asylum. He says he does not expect to get deported.
"Even if I have to spend 25 or 30 years on prison, I will not return to Honduras, says Oscar.
According to the Department of Homeland Security, only 1.4 percent of all Central American family units will be sent back to their home countries."
The Rio Grande Valley sector is the busiest in the U.S. for illegal entries. Ortiz estimates there are currently about 850 arrests a day here and counting. Agents here say the numbers are not sustainable or safe.
Right now, Ortiz says about a hundred migrants who cross illegally go undetected or escape.
To slow the constant flow of illegal traffic, U.S. Border Patrol wants more people, more technology and more wall to nab or deter those avoiding legal points of entry.
"94 percent of my traffic happens on the west side where I have very little infrastructure and almost no permanent technology whatsoever, says Ortiz."
Ortiz made the case to President Trump, who recently visited the Southern Border saying, "Just yesterday, we apprehended 133 people from countries other than Central America and Mexico. That includes individuals from India, Pakistan, China, Romania, Ecuador, Nicaragua, on and on and on."
Though Democrats are fighting construction of a wall with Mexico, construction is moving forward on 33 miles of new barriers Congress funded last year here.
"I’m not a believer that you need to build infrastructure everywhere. But in areas where you have populations where you were very close to the river on both sides, you certainly need to have something to slow the traffic down. That’s what’s going to happen here, says Ortiz.
But both sides agree even a barrier along the entire U.S. Mexico border won't stop everyone. But Ortiz says it would help agents do their jobs better.
"We just want to know America has our back," says Ortiz.
Meanwhile, as the debate rages on in Washington, D.C., President Trump's Emergency Declaration could free up money to build hundreds more miles of barrier here without approval from Congress.
Wisconsin Gov. Tony Evers (D) and Attorney General Josh Kaul are part of a multi-state lawsuit challenging the President's national emergency declaration to build a border wall.
In a statement released in mid-March, the governor stated - in part - "there is not enough evidence to support the claim there is a national security crisis at the southwest border."
A day after Wisconsin joined the lawsuit, the U.S. Senate agreed with the House to overturn the President's emergency declaration over the U.S. border. Sen. Tammy Baldwin (D-Wis.) joined all Democrats and 12 Republicans to overturn the declaration.
