Border enforcement has always been a sticking point for the Obama administration. Following the administration's partial victory against Arizona's SB 1070, it became an even bigger point as Obama announced DHS deportation policies would no longer be applicable in Arizona.
But now, concerns over the border have hit new levels, as Secretary of Homeland Defense Janet Napolitano has admitted that terrorists intending to do harm to this country are entering via our southern border "from time to time."
Napolitano was responding to a question from Rep. Ron Barber (D-AZ), who asked: "Is there any credible evidence that...terrorists are, in fact, crossing our southern border with the intent to do harm to the American people?" To this question Napolitano answered: "There have been...from time to time, and we are constantly working against different and evolving threats involving various terrorists groups and various ways they may seek to enter the country."
