Dr. Ben Carson tells Breitbart News America’s “worst nightmare” might be “unfolding before our eyes.”

The 2016 GOP presidential contender is responding to an exclusive report from Breitbart Texas about eight Syrians being caught at the U.S. border with Texas.

“Fresh on the heels of multiple warnings, it seems our worst nightmare may be unfolding before our eyes,” Carson said in an emailed statement in response to the Breitbart Texas report on Thursday. “Mr. President, do your job, protect America’s borders. Stop the dangers of illegals at our borders, and halt your plans to bring 10,000 Syrian refugees to our great nation.”

On Wednesday evening, Breitbart Texas’ Brandon Darby—quoting the Border Patrol agents’ union—reported that there were eight Syrians caught at the border in Laredo, Texas.

“Two federal agents operating under the umbrella of U.S. Customs and Border Protection (CBP) are claiming that eight Syrian illegal aliens attempted to enter Texas from Mexico in the Laredo Sector,” Darby wrote.

The federal agents spoke with Breitbart Texas on the condition of anonymity, however, a local president of the National Border Patrol Council (NBPC) confirmed that Laredo Border Patrol agents have been officially contacting the organization with concerns over reports from other federal agents about Syrians illegally entering the country in the Laredo Sector. The reports have caused a stir among the sector’s Border Patrol agents.

The Department of Homeland Security (DHS) on Thursday confirmed the Breitbart Texas report.

“DHS confirms that on Tuesday, members of two Syrian families, two men, two women and four children, presented themselves at a port of entry in Laredo,” a DHS statement to NBC News reads.
