A senior official in the Department of Homeland Security tells FOX News that nearly four hundred migrants crossed the Southern border with help from an ISIS-affiliated smuggling ring. DHS says that they believe it is more of a network taking advantage of migrants wanting to enter the U-S and not a terror operation. Homeland Security Secretary Alejandro Mayorkas at a briefing with reporters to tout decreasing numbers of illegal crossings said the report was 'incorrect' but didn't not offer details on why he feels that way.

FOX’s Eben Brown speaks with Charles Marino, former advisor to the DHS Secretary Janet Napolitano, Chief Executive Officer of Sentinel, and author of 'Terrorists on the Border and in Our Country', about the report and the level of concern we could have about a terrorist threat at the border.
