The bill, which has stirred up internet privacy watchdogs and sites like Reddit, followed closely in the footsteps of the last unsuccessfully proposed privacy bills, the Stop Online Piracy Act (SOPA) and Protect I.P. Act (PIPA). SOPA and PIPA met their end last year after Senate Majority Leader Harry Reid canceled debate following pressure and protests from Internet companies such as Wikipedia, Google, and Reddit.

The heat on CISPA hasn't been as hot as the pressure put on SOPA and PIPA last year, but Sen. Jay Rockefeller (D-WV) who is the Chairman of the U.S. Senate Committee on Commerce, Science and Transportation says that CISPA's privacy protections are "insufficient" and a committee aid confirmed to CNET that "Rockefeller believes the Senate will not take up CISPA."
