FBI Director Robert S. Mueller III told Congress on Thursday that two controversial provisions in the 2001 anti-terrorism law known as the Patriot Act will be especially important for adapting to the threat of domestic radicalization and the challenges of a wireless communications world.
Both Mueller and Matthew G. Olsen, director of the National Counterterrorism Center, told the House Select Intelligence Committee that U.S. citizens and residents, inspired by groups like al Qaeda but lacking any actual contacts that intelligence agencies could track, present a serious national security threat.
“That is probably the greatest challenge that we face,” Olsen said.
