You may have read of the shocking allegations made by Rep. Duncan Hunter on Tuesday when he claimed that 10 Islamic State terrorists had been apprehended at the southern border.

“There’s nobody talking about it,” Rep. Hunter told Fox. “If you really want to protect Americans from ISIS, you secure the southern border. It’s that simple…They caught them at the border, therefore we know that ISIS is coming across the border. If they catch five or ten of them then you know there’s going to be dozens more that did not get caught by the border patrol.”

Not so, says DHS:

“The suggestion that individuals who have ties to ISIL have been apprehended at the Southwest border is categorically false, and not supported by any credible intelligence or the facts on the ground,” said DHS spokesperson Marsha Catron. “DHS continues to have no credible intelligence to suggest terrorist organizations are actively plotting to cross the southwest border.”

Hunter claimed to get his information from a high level DHS source. And now, Judicial Watch has confirmed at least part of the story:

Islamic terrorists have entered the United States through the Mexican border and Homeland Security sources tell Judicial Watch that four have been apprehended in the last 36 hours by federal authorities and the Texas Department of Public Safety in McAllen and Pharr.

JW confirmed this after California Congressman Duncan Hunter, a former Marine Corp Major and member of the House Armed Services Committee, disclosed on national television that at least ten Islamic State of Iraq and Greater Syria (ISIS) fighters have been caught crossing the Mexican border in Texas. The veteran lawmaker got the astounding intel straight from U.S. Customs and Border Protection (CBP), the Homeland Security agency responsible for guarding the 1,933-mile southern border.

“If you really want to protect Americans from ISIS, you secure the southern border,” Hunter proclaimed on a national cable news show this week. “It’s that simple. ISIS doesn’t have a navy, they don’t have an air force, they don’t have nuclear weapons. The only way that ISIS is going to harm Americans is by coming in through the southern border – which they already have.” The three-term congressmen went on: “They aren’t flying B-1 bombers, bombing American cities, but they are going to be bombing American cities coming across from Mexico.”

In late August JW reported that Islamic terrorist groups are operating in the Mexican border city of Ciudad Juarez and planning to attack the United States with car bombs or other vehicle borne improvised explosive devices (VBIED). High-level federal law enforcement, intelligence and other sources confirmed to JW that a warning bulletin for an imminent terrorist attack on the border has been issued. Agents across a number of Homeland Security, Justice and Defense agencies have all been placed on alert and instructed to aggressively work all possible leads and sources concerning this imminent terrorist threat.

Ther's an interesting bureaucratic dynamic at work. Agents with the US Customs and Border Protection service have been complaining for years about our porous southern border. Unlike the rest of DHS immigration agencies, they have been vocal about enforcing border security.

Perhaps the entry of these terrorists was the last straw. Knowing that DHS would sweep it under the rug, CBP leaked the info first to the congressman and then to JW. And the fact that they were willing to go on the record makes the DHS look like a bunch of liars.

It may be that we were keeping the apprehension of these terrorists secret until we could interrogate them to discover if they have any associates in the US and what was their plot. But once the information was out, DHS had no cause to lie anymore.

And you know that if 4 were caught, there are others who were successful in breaching our border security. It's unsettling to contemplate the lack of urgency by this government to shore up our security at a time when terrorists are able to cross the border with impunity.
