The border is still out of control. Only last March, we read with great concern about a mass rush of illegal immigrants storming the border at El Paso, Texas, overwhelming law enforcement and invading the United States.

On Monday, we learned that over 100 suspected Tren de Aragua (TdA) gang members were part of that invasion.

More than 100 suspected members of Tren de Aragua (TdA) were a part of the group that violently stormed the border at El Paso, Texas in March — as Texas Gov. Greg Abbott has declared the Venezuelan prison gang a foreign terrorist organization.

“Earlier this year, more than 100 suspected TdA members were arrested after the riots at the El Paso border, when immigrants assaulted the Texas National Guard,” Gov. Abbott revealed Monday, as he announced a plan to crack down on the group’s growing presence across the US.

The wild border rush, captured exclusively by The Post, saw hundreds of illegal migrants break through razor wire to dash into the US — shoving Lone Star State troops in the process.

Texas Governor Greg Abbott isn't waiting for the Harris/Biden administration to act. He has his own plan, one which the Harris/Biden administration will almost certainly oppose.

The plan would institute a 10-year mandatory minimum sentence for TdA smugglers bringing people into Texas, create a database to track members of the gang and beef up law enforcement’s capabilities to target the transnational criminal organization.

“Our goal among law enforcement in the state of Texas is to defend our state from the growing threat of TdA. We are not going to allow them to use Texas as a base of operations to terrorize our citizens,” he fumed.

But it gets worse — much, much worse. Here's the real outrage:

Following the March melee, a judge dismissed charges against 211 of the migrants accused of rioting and then Immigration and Customs Enforcement (ICE) let dozens of them go free into the US.

Since then, the gang has created footholds across the country, allegedly taking over apartments in Colorado, seizing hotels near the Texas border in El Paso and shooting cops in New York.

Why were any charges dismissed? These people staged a violent invasion of the United States of America. Every one of them. They assaulted law enforcement officers. They destroyed U.S. government property. Every single one of these people should be, at a minimum, deported; in a more just world, every one of them would be occupying a cell in a federal prison.

None of that has happened. And now, because of the feckless non-enforcement of federal immigration law, over 100 vicious gang members are wandering free in the United States.

This is just one more example of a troubling — and enormous — issue. The oozing open sore that is our southern border is a huge risk to American security and the American people. The Harris/Biden administration has disregarded this threat, and it's coming to the point where it's hard to credit this being anything but a deliberate act.

I'll say it again: This is a national security matter. Too many of these illegal aliens are unknown quantities: We don't know who they are, where they come from, where they are going, or what they intend to go when they get there.
