"A US Senate committee has approved a wide-ranging cybersecurity bill that some critics have suggested would give the US president the authority to shut down parts of the Internet during a cyberattack...The bill, introduced earlier this month, would establish a White House Office for Cyberspace Policy and a National Center for Cybersecurity and Communications, which would work with private US companies to create cybersecurity requirements for the electrical grid, telecommunications networks and other critical infrastructure.
The bill also would allow the US president to take emergency actions to protect critical parts of the Internet, including ordering owners of critical infrastructure to implement emergency response plans, during a cyber-emergency. The president would need congressional approval to extend a national cyber-emergency beyond 120 days under an amendment to the legislation approved by the committee.
The legislation would give the US Department of Homeland Security authority that it does not now have to respond to cyber-attacks, Lieberman, a Connecticut independent, said earlier this month."
