Launching new and sophisticated efforts to block terrorists and criminals from reaching the United States and to protect the homeland from violent extremism and targeted violence, including in our schools and gathering places
Sought and received new authorities to enable the Department to execute new seen and unseen security measures to protect Americans against emerging threats, from weaponized drones to chemical and biological weapons
