Texas Department of Public Safety chief Steve McCraw testified before lawmakers in Washington last week.
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.
