Lawmakers worry about terrorists on Twitter

Lawmakers on the House Homeland Security subcommittee on Counterterrorism and Intelligence probed the threat of terrorists using social media tools such as Facebook and Twitter to attract followers at a hearing. They noted that Anwar al Awlaki, known as the "Bin Laden of the Internet," recruited radicals online. The lawmakers pointed to "Jihad Jane," who allegedly plotted to kill a Swedish cartoonist after viewing and commenting on radical YouTube videos. Brian Michael Jenkins, a senior adviser at the RAND Corporation, told the subcommittee that al-Qaida sees the Web as a critical tool for advancing its agenda.
