It is ridiculous to suggest that the chairman of the House committee responsible for homeland security is out of line to investigate the subject of radicalization in the American Muslim community.

Recent attacks by al-Shabab in Uganda and the court hearing of an American charged with trying to join the jihad in Somalia are bad signs that a new transnational terrorist network is taking shape in East Africa, and President Obama has made the problem worse by ordering the killing of the man who could have helped disrupt and destroy the network.
