Seven that we know of because we caught one Al-Qaeda affiliated human smuggler. Open borders will lead to disaster soon. From KRGV:

WASHINGTON, D.C. – Texas Department of Public Safety chief Steve McCraw testified before lawmakers in Washington on Wednesday.

He says the majority of people from terrorist sponsored countries are getting into the U.S. along the Texas border.

He pointed to Ahmed Muhammad Dhakane as one of those terrorists.

He asked for asylum at an international crossing in Brownsville in 2008. Halfway through the request, Federal Bureau of Investigation Agents took a closer look at him. They say he was an Al Qaeda terrorist and human smuggler. Dhakane admits to smuggling seven members of Al Qaeda into the U.S.

He’s been sentenced to 10 years behind bars for lying on his asylum application.

“The San Antonio federal case of the Somalian is a significant concern. It underscores this is not make believe, you can’t secure your borders from foreign nationals penetrating them undetected and uninterdicted. It constitutes a threat,” says McCraw.

An understatement. Political correctness and business interest who love cheap labor from a de facto slave class will be responsible for the next terror attack in America. Here’s a video report.
