"On September 25, the House of Representatives passed the following three pieces of legislation:  H.R. 6620, the Protecting Critical Infrastructure Against Drones and Emerging Threats Act, which would require the Department of Homeland Security (DHS) to prepare assessments of the threats presented by unmanned aircraft systems (often called drones) and other emerging threats associated with such new technologies;  H.R. 6735, the Public-Private Cybersecurity Cooperation Act, which would require DHS to establish procedures for people or organizations to report vulnerabilities in the department's information systems; and  H.R. 6740, the Border Tunnel Task Force Act, which would direct DHS to establish task forces to combat threats from cross-border tunnels; the task forces could include personnel from federal, state, local, and tribal agencies. CBO [Congressional Budget Office] estimates that enacting the legislation would not significantly affect spending by DHS in any fiscal year because the department could largely implement each act with existing personnel."
