U.S. Senator Ben Sasse, a member of the Senate Homeland Security Committee, issued the following statement regarding the arrest of a Washington, D.C. Metro Transit police officer, Nicholas Young, charged with aiding ISIS. According to authorities, the FBI monitored Young since 2010. 

"While Americans are disturbed to learn that a police officer would aid ISIS, we are grateful that the FBI was alert and active. This is a sobering reminder of the vigilance required to combat crowd-sourced terror. Our enemies’ old, top-down strategy no longer defines our threats. The intelligence community does not exclusively hunt card-carrying members of ISIS and al-Qa’ida. Our challenge is greater and today the FBI has met it forcefully."
