The Wall Street Journal reports ever since former NSA contractor Edward Snowden revealed the breadth of U.S. electronic surveillance, tensions have simmered between the government and technology companies over access to users’ online communication. Congress is now raising the stakes. The Senate Intelligence Committee included language in an annual intelligence-funding reauthorization bill last month that would require companies such as Google Inc., Facebook Inc. and Twitter Inc. to disclose any content they spot on their networks that could indicate terrorist activity. The proposed measure could cover everything from emails to tweets to videos. The new provision is modeled on existing federal requirements for policing child pornography. However tech company officials say weeding out terrorist messages is much more complex.
