Interesting, a bill to allow POTUS to "declare a cyber-security emergency and order the limitation or shutdown of Internet traffic to and from" the designated or private-sector system or network.

Bill Would Grant President Unprecedented Cyber-security Powers

The bill is reportedly vague as to what constitutes a critical for national security network, but I don't see it as a far stretch that "someone" would decide that "domestic terrorists" are communicating via sites like AR15.com or Zombie Squad, and orders them shutdown. Sounds like way too much un-Constitutional power to me. (I know, living document, founding fathers never envisioned, blah blah blah... Bullshit excuses.)
